Problem 35P

PROBLEM 35P

For the reaction shown, calculate how many grams of each product form when the given amount of each reactant completely reacts to form products. Assume there is more than enough of the other reactant.

2 Al(s) + Fe2O3(s) → Al2O3(s) + 2 Fe(l)

(a) 4.7 g Al

(b) 4.7 g Fe2O3

Step-by-Step Solution:

Solution 35P

Here, we are going to calculate the mass of product formed when the given amount of each reactant completely reacts.

Step 1:

The given reaction is:

2Al(s) + Fe2O3(s) → Al2O3(s) + 2Fe(l)

Given, mass of Al = 4.7 g

Molar mass of Al = 26.98 g/mol

Therefore, number of moles of Al = given mass / molar mass

= $\frac{4.7\ g}{26.98\ g/mol}$ = 0.17 mol

From the above reaction, it is seen that 2 moles of Al produces 1 mole of Al2O3 and 2 moles of Fe.

Therefore, 0.17 mol of Al will produce (½ x 0.17 = 0.085) mol of Al2O3 and 0.17 mol of Fe.
