Answer:

0.20 moles

Explanation:

In order to solve this problem it is necessary to keep in mind the definition of molarity:

If we input the data given by the problem we're left with:

Meaning that we can proceed to calculate the number of moles:

The number of moles of glucose ([tex]C_6H_{12}O_6[/tex]) in 0.500 Liters of a 0.40 M solution is 0.2 moles.

Given the following data:

To determine the number of moles of glucose ([tex]C_6H_{12}O_6[/tex]) in 0.500 Liters of a 0.40 M solution:

Mathematically, the molarity of a solution is given by the formula:

[tex]Molarity = \frac{number\;of\;moles}{Volume \;in\;liters}[/tex]

Making number of moles the subject of formula, we have:

[tex]Number\;of\;moles = Molarity \times Volume[/tex]

Substituting the given parameters into the formula, we have;

[tex]Number\;of\;moles = 0.40 \times 0.500[/tex]

Number of moles = 0.2 moles.

Answer:

[tex]\boxed {\boxed {\sf 0.5000 \ mol \ NaCl}}[/tex]

Explanation:

We are asked to convert grams to moles. We must use the molar mass or the grams in 1 mole of a substance. These values are found on the Periodic Table as the atomic mass, but the units are grams per mole (g/mol) instead of atomic mass units (amu).

We are given the compound sodium chloride or NaCl. Look up the molar masses of the individual elements.

The formula for the compound does not contain any subscripts, so there is 1 mole of each element in 1 mole of the compound. Add the molar masses together to find sodium chloride's molar mass.

Now we can use the molar mass to create a ratio. We know there are 58.4397693 grams of NaCl in 1 mole of NaCl.

[tex]\frac {58.4397693 \ g \ NaCl}{ 1 \ mol \ NaCl}[/tex]

Multiply by the number of grams provided in the problem: 29.22

[tex]29.22 \ g\ NaCl*\frac {58.4397693 \ g \ NaCl}{ 1 \ mol \ NaCl}[/tex]

Flip the ratio so the units of grams of NaCl cancel.

[tex]29.22 \ g\ NaCl*\frac { 1 \ mol \ NaCl}{58.4397693 \ g \ NaCl}[/tex]

[tex]29.22*\frac { 1 \ mol \ NaCl}{58.4397693}[/tex]

[tex]\frac {29.22}{58.4397693} \ mol \ NaCl[/tex]

[tex]0.5000019738 \ mol \ NaCl[/tex]

The original measurement of grams has 4 significant figures, so our answer must have the same. For our answer, that is the ten-thousandth place. The 0 to the right of this place (0.5000019738) tells us to leave the 0 in the ten-thousandth place.

[tex]0.5000 \ mol \ NaCl[/tex]

There are approximately 0.5000 moles of sodium chloride in a 29.22 gram sample of sodium chloride.

My name is Andreas Vesalius and I'm a 16th-century Flemish anatomist, physician, and author of one of the most influential books on human anatomy, De Humani Corporis Fabrica Libri Septem. I am often referred to as the founder of modern human anatomy. I was born in Brussels, December 31, 1514 which was then part of the Habsburg Netherlands. I was a Flemish doctor who was notable for my contribution to the science of anatomy of the human body. I was the first to perform public dissection on a human corpse, a practice that was unusual in the Middle Ages due to spiritual beliefs.

Answer:

150 mL

Explanation:

From the question given above, the following data were obtained:

Molarity of stock solution (M₁) = 10 M

Volume of diluted solution (V₂) = 3 L

Molarity of diluted solution (M₂) = 0.5 M

Volume of stock solution needed (V₁) =?

The volume of stock solution needed can be obtained as follow:

M₁V₁ = M₂V₂

10 × V₁ = 0.5 × 3

10 × V₁ = 1.5

Divide both side by 10

V₁ = 1.5 / 10

V₁ = 0.15 L

Finally, we shall convert 0.15 L to mL. This can be obtained as follow:

1 L = 1000 mL

Therefore,

0.15 L = 0.15 L × 1000 mL / 1 L

0.15 L = 150 mL

Therefore, the volume of the stock solution needed is 150 mL

Neutrons and protons

Explanation:

There are three fundamental subatomic particles, these are;neutrons protons and electrons.

Ernest Rutherford successfully showed that every atom does possess a central core that contain positively charged particles (protons) called the nucleus. Chadwick later discovered the existence of neutrons.

Both protons and neutrons are found in the nucleus. Z represents the nucleus of the boron atom and houses the neutrons and protons of the boron atom.

Answer:

It would be to low

Explanation:

If some salt were accidently spilled as it was transferred from  balance to  cup  calculated enthalpy of solution of salt be too low as there will be loss in mass  which would lead less solubility of salt and hence less enthalpy.

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.
