How many grams of iron can be obtained from a 268-g sample of iron(iii) oxide?

187.44 g

Explanation:

Calculation of the moles of as:-

Mass = 268 g

Molar mass of iron(III) oxide = 159.69 g/mol

The formula for the calculation of moles is shown below:

Thus,

According to the formula, 1 mole of iron(III) oxide has 2 moles of iron.

Also,

1.67825 mole of iron(III) oxide has moles of iron.

Moles of iron = 3.3565 moles

Molar mass of iron = 55.845 g/mol

Mass=Moles*Molar mass = = 187.44 g

187.44 g of iron can be obtained from a 268-g sample of iron(III) oxide.

the answer would be a

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
