Question

Two tonnes of an iron ore containing 94% of Fe2O3 produces iron in pure state. Calculate the weight of iron.

Answer 1

Answer:

1314 kg

Explanation:

94% of 2 tonnes comes out to be 1880 kg.

The molar mass of Fe2O3

= 2 * 55.8 (molar mass of iron) + 3 * 16 (molar mass of oxygen)

= 159.6

Percentage of iron by mass

= (2 * 55.8)/ 159.6

= (111.6)/ 159.6

Thus total mass of iron = 1880 * 111.6/159.6 = 1314 kg
