Explanation / Answer

13)

Molar mass of Fe2O3,

MM = 2*MM(Fe) + 3*MM(O)

= 2*55.85 + 3*16.0

= 159.7 g/mol

use:

mass of Fe2O3,

m = number of mol * molar mass

= 0.5 mol * 1.597*10^2 g/mol

= 79.8 g

Answer: A

14)

1 mol of Fe2O3 has 3 moles of O

So,

number of moles of O = 3*number of moles of Fe2O3

= 3*0.500

= 1.50 moles

Number of atoms of O = number of moles of O * Avogadro’s number

= 1.50 * 6.022*10^23

= 9.03*10^23 atoms

Answer: 9.03*10^23 atoms

15)

1 mol of Fe2O3 has 3 moles of O

So,

number of moles of O = 3*number of moles of Fe2O3

= 3*0.500

= 1.50 moles

Molar mass of O = 16 g/mol

use:

mass of O,

m = number of mol * molar mass

= 1.5 mol * 16 g/mol

= 24 g

Answer: 24 g
