Need help ASAP..... (0.567 liters of H2O is how many moles of H2O? HINT: 1 mL H20 = 1 gram
H20)

Answers

Answer:

31.5 moles

Explanation:

Volume of H2O = 0.567 L

Number of mole of H2O =.?

Next, we shall convert 0.567 L to millilitres (mL). This can be obtained as follow:

1 L = 1000 mL

Therefore,

0.567 L = 0.567 L × 1000 mL / 1 L

0.567 L = 567 mL

Thus, 0.567 L is equivalent to 567 mL.

Next, we shall convert 567 mL to grams (g). This can be obtained as follow:

1 mL of H2O = 1 g

Therefore

567 mL of H2O = 567 g of H2O

Finally, we shall determine the number of mole in 567 g of H2O. This can be obtained as follow:

Mass of H2O = 567 g

Molar mass of H2O = (2×1) + 16

= 2 + 16 = 18 g/mol

Mole of H2O =?

Mole = mass /Molar mass

Mole of H2O = 567 /18

Mole of H2O = 31.5 moles

How many moles are in 2.16 x 1026 atoms of magnesium?*

Answers

Answer:

The answer is 358.80 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\ [/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{2.16 \times {10}^{26} }{6.02 \times {10}^{23} } \\ = 358.80398671...[/tex]

We have the final answer as

358.80 moles

Question 20 of 66
Which of the following species has the same number of protons as Fe3+?
A) Mn3+
B) Co2+
C) Fe2+
D) Nit
E) CO3+

Answers

Okay, so you know that the number of protons never changes for a certain element. It defines what the element is, so as the element in the question is iron (fe) we know that the answer must also be iron. Therefore the answer is C. The 2+ and 3+ do not matter as these show that there are different numbers of electrons.
If you have any questions please let me know.

Fe²⁺ has the same number of protons as Fe³⁺.

In order to know the number of protons of a species, we need to look for the atomic number (Z) in the Periodic Table.

The atomic number of Fe is 26, so it has 26 protons. Since protons are in the nucleus, they are not lost nor gained. Fe³⁺ results from Fe losing 3 electrons, but it has 26 protons as well.

Taking this into account, let's consider the number of protons of the following species:

A) Mn³⁺. It has 25 protons like Mn (Z = 25).

B) Co²⁺. It has 27 protons like Co (Z = 27).

C) Fe²⁺. It has 26 protons like Fe (Z = 26).

D) Ni. It has 28 protons (Z = 28).

E) Co³⁺. It has 27 protons like Co (Z = 27).

Fe²⁺ has the same number of protons as Fe³⁺.

Doing Calculations The metal thallium occurs naturally as 30 percent thallium-203 and 70
percent thallium-205. Calculate the atomic mass of thallium. Enter your numerical answer in
the blank provided please help

Answers

Answer:

Average atomic mass of thallium = 204.4 amu.

Explanation:

Given data:

Abundance of thallium-203 = 30%

Abundance of thallium-205 = 70%

Average atomic mass = ?

Solution:

Average atomic mass of thallium = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  / 100

Average atomic mass of thallium = (30%×203)+(70%×205) /100

Average atomic mass of thallium =  6090 + 14350 / 100

Average atomic mass of thallium = 20440 / 100

Average atomic mass of thallium = 204.4 amu.

Calcium reacts with oxygen to make calcium oxide, CaO. What is the theoretical yield (g) of CaO(s) that could be prepared from 7.75 g of Ca(s) and 2.44 g of O2(g)

Answers

Answer:

Explanation:

2Ca    +    O₂   =    2CaO

80 g     32 g         112 g

given amount of Ca = 7.75 g

it will require oxygen =  32 x 7.75 / 80 = 3.1 g

but available oxygen = 2.44 so oxygen is the limiting reagent .

32g oxygen reacts with calcium to give 112 g of calcium oxide

2.44 gram of oxygen reacts with calcium to give 112 x 2.44 / 32 of CaO .

= 8.54 gram .

Theoretical yield of CaO = 8.54 gram.
