Calculate the mass of iron which can be obtained with an adnaulenny iron axid (lll) masai

Calculate the mass of iron which can be obtained with an adnaulenny iron axid (lll) masai 150 grams of aluminum-reinforced methods.

To solve the problem, let’s make calculations:
1. Let’s compose the equations by the electronic balance method:
Fe2O3 + 2Al = 2Fe + Al2O3 – ОВР, iron was obtained by the method of aluminothermy;
2. Calculation of molar masses:
M (Fe2O3) = 159.6 g / mol;
M (Fe) = 55.8 g / mol.
3. Determination of the number of moles Fe2O3, Fe according to the formula:
Y (Fe2O3) = m / M = 150 / 159.6 = 0.93 mol;
0.93 mol (Fe2O3) – X mol (Fe);
-1 mol -2 mol from here, X mol (Fe) = 0.93 * 2/1 = 1.82 mol.
4. Find the mass of the product – Fe:
m (Fe) = Y * M = 1.82 * 55.8 = 101.55 g.
Answer: during the reaction, iron was obtained with a mass of 101.55 g.
