Determine the mass of pure Fe2O3 in 1 ton of magnetic iron ore containing 24% of impurities.

Iron oxide mass – 1 ton.

Mass fraction of impurities – 24%.

Determine the mass of pure iron oxide.

To do this, we determine the mass fraction of pure iron oxide.

100% – 24% = 76%.

Let’s convert the mass to kilograms.

1 t = 1000 kg.

Therefore, the mass of iron oxide is 1000 kg.

Determine the mass of the number iron oxide.

1000 kg of iron oxide – 100%.

X g of iron oxide is 76%.

Let’s define the unknown value of x.

X = 1000 * 76: 100 = 760 kg.

Therefore, the mass of pure sulfur oxide is 760 kg.

Answer: 760 kg.
