| 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.
