Answer:

Explanation:

Mass 1 mole of CO

C = 12

O = 16

m = 28

Mols of 91.72 grams

m = given Mass / Molar Mass

m = 91.72 / 28

m = 3.28 mols

Molecules

1 mol of anything is 6.02 * 10^23 molecules (in this case)

3.28 mol of CO = x

1/3.28 = 6.02*10^23/x      Cross multiply

x = 3.28 * 6.02 * 10^23

x = 1.97 * 10^24
