Answer 2

Explanation:

Mass of iron in 1 gram of hydrated salt = 0.2014 g

Mass of sulfur in 1 gram of hydrated salt = 0.1153 g

Mass of oxygen in 1 gram of hydrated salt = 0.2310 g

Mass of water in 1 gram of hydrated salt = 0.4532 g

Percentage composition of an element:

$\frac{\text{Mass of an element}}{\text{Mass of the compound}}\times 100$

Percentage composition of molecule:

$\frac{\text{Mass of molecule}}{\text{Mass of the compound}}\times 100$

Percentage of iron in hydrated salt:

$\frac{0.2014 g}{1 g}\times 100=20.14\%$

Percentage of sulfur in hydrated salt:

$\frac{0.1153 g}{1 g}\times 100=11.53\%$

Percentage of oxygen in hydrated salt:

$\frac{0.2310 g}{1 g}\times 100=23.10\%$

Percentage of water molecules in hydrated salt:

$\frac{0.4532 g}{1 g}\times 100=45.32\%$
