If a naturally occurring sample of an unidentified element is found to contain three isotopes (A, B, and C) and consists of 90.5% isotope A (mass number 20), 0.3% isotope B (mass number 21), and 9.3% isotope C (mass number 22), the atomic weight of the element measured from the sample will be greater than 21 amu.
To calculate the average atomic mass, multiply the fraction through the mass number for every isotope, then add them together. Whenever we do mass calculations concerning elements or compounds (combos of elements), we usually use average atomic loads.
For instance, carbon-14 is a radioactive isotope of carbon that has six protons and 8 neutrons in its nucleus. We name it carbon-14 because the overall range of protons and neutrons within the nucleus also called the mass number, provides up to fourteen (6+8=14).
Together, the quantity of protons and the range of neutrons determine an detail's mass variety. Due to the fact, that an element's isotopes have barely unique mass numbers, the atomic mass is calculated by obtaining the suggested mass numbers for its isotopes.

7. If you start with 3.20 mol of Li3N and 9.0 mol water, how many moles of NH3 will be formed?
Li3N + 3H2O ----> NH3 + 3LiOH
Taking into account the reaction stoichiometry, 3 moles of NH₃ will be formed.
Reaction stoichiometryIn first place, the balanced reaction is:
Li₃N + 3 H₂O → NH₃ + 3 LiOH
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
Li₃N: 1 moleH₂O: 3 molesNH₃: 1 mole LiOH: 3 molesLimiting reagentThe limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.
Limiting reagent in this caseTo determine the limiting reagent, it is possible to use a simple rule of three as follows: if by stoichiometry 1 mole of Li₃N reacts with 3 moles of H₂O, 3.20 moles of Li₃N reacts with how many moles of H₂O?
[tex]moles of H_{2} O=\frac{3.2 moles of Li_{3}Nx 3 moles of H_{2} O}{1 mole of Li_{3}N}[/tex]
moles of H₂O= 9.6 moles
But 9.6 moles of H₂O are not available, 9 moles are available. Since you have less moles than you need to react with 3.20 moles of Li₃N, H₂O will be the limiting reagent.
Mass of NH₃ formedConsidering the limiting reagent, the following rule of three can be applied: if by reaction stoichiometry 3 moles of H₂O form 1 mole of NH₃, 9 moles of H₂O form how many moles of NH₃?
[tex]molesof NH_{3} =\frac{9 moles H_{2} Ox1 mole of NH_{3}}{3 moles H_{2} O}[/tex]
moles of NH₃= 3 moles
Finally, 3 moles of NH₃ will be formed.

What is a proton?Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge.
If it has 23 protons, then its proton number (also know as its atomic number) is 23. You can look that symbol up in your periodic table.
If it has 21 electrons then it has a net charge of 23(+) - 21. So we know the ionisation state of the species, and we can record that as a superscript after the symbol for the species.

In a Base catalyst elimination, the base extracts a proton and the leaving group leaves simultaneously. In a Concentrated process, the leaving group leaves the base abstracts a proton.
Just as there are two mechanisms of substitution (SN2 and S N1), there are two
mechanisms of elimination (E2 and E1).
E2 mechanism — bimolecular elimination
E1 mechanism — unimolecular elimination
The E2 and E1 mechanisms differ in the timing of bond cleavage and bond formation, analogous to the SN2 and S N1 mechanisms.
E2 and S N2 reactions have some features in common, as do E1 and SN1 reactions.
Base removes a proton from the β-carbon atom,
while the halogen atom leaves from the α-carbon resulting in the formation of a π-bond. Such eliminations are also called β-eliminatione liminations are also called β elimination reactions
In a base-catalyzed elimination reaction, the base takes away a proton from the β position of the leaving group (the group that goes away with the bonding pair of electrons) and a double bond is formed. When the base is bulky it prefers to take away the proton from the less hindered position.

What is the concentration of ammonia in a solution if 24.4 mL of a 0.117 M solution of HCl are needed to titrate a 100.0 mL sample of the solution
Answer: The concentration of ammonia is 0.0286M.
Explanation:
The diluted equation is presented as: [tex]M_{s} V_{s} =M_{d} V_{d}[/tex].
~M= Molarity (labeled as M)
~V= Volume (labeled in L)
~s= stock solution (what you started with)
~d= diluted solution (what you now have)
Now that we have our definitions, we can knowingly plug the information into the formula shown above.
[tex]0.117M*24.4mL=M_{d} *100mL[/tex]
We have the information plugged in, but the volume must be measured into liters, not milliliters. We can fix that by converting it. To convert milliliters to liters, you divide the milliliters by 1000.
[tex]24.4mL/1000=0.0244L[/tex] [tex]100mL/1000=0.1L[/tex]
Now that the volumes are in liters, let's plug that into the equation.
[tex]0.117M*0.0244L=M_{d} *0.1L[/tex]
We are now ready to solve the concentration with this equation!
[tex]M_{d} =\frac{0.117M*0.0244L}{0.1L}[/tex] [tex]M_{d} =0.0286M[/tex]
With all of the steps shown above, we can conclude that the new concentration of ammonia is 0.0286M.

What is the strongest type of intermolecular force between solute and solvent in each solution? (a) CH3OCH3(g) in H2O(l)
The strongest type of intermolecular force between solute and solvent in CH3OCH3(g) in H2O(l) is H-bond and ion-induced dipole.
What is H-bond?
Hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom.
It comes about as a result of the attraction between a hydrogen atom that is covalently attached to a very electronegative atom, like an N, O, or F atom, and another extremely electronegative atom.
Hydrogen is covalently joined to the more electronegative oxygen atom in water molecules (H2O). Therefore, the dipole-dipole interactions between the hydrogen atom of one water molecule and the oxygen atom of another H2O molecule are what cause hydrogen bonding to form in water molecules.

Calculate the work (KJ) done during a reaction in which the internal volume contracts from 83 L to 13 L against an outside pressure of 4.4 atm.
-31.2 kJ is the work done during a reaction in which the internal volume contracts from 83 L to 13 L against an outside pressure of 4.4 atm.
How to calculate the work done on or by a gas ?It is represented by the equation
W = PΔV
where,
W = Work done
P = Pressure
ΔV = Change in volume (V₂ - V₁)
Now put the values in above formula we get
W = PΔV
= 4.4 atm × (13 L - 83 L)
= 4.4 atm × (-70 L)
= -308 atm L
Now change L atm into J
= -308 × 101.3 J [L × atm = 101.3 J]
= -31200.4 J
= -31200.4 × 10⁻³ kJ
= -31.2 kJ
Thus from the above conclusion we can say that -31.2 kJ is the work done during a reaction in which the internal volume contracts from 83 L to 13 L against an outside pressure of 4.4 atm.
