4) Find the mass of 1.46 mol of Al2(SO4)3.

1.46mol of Al2(SO4)3 weights 499.5 grams

Explanation:

First we will find the gram formula mass of Al2(SO4)3.

Al * 2 = 26.98 g/mol * 2 = 53.96 g

SO4 * 3 = 96.06 g/mol * 3 = 288.18

53.96 + 288.18 = 342.14 g

That is the mass of 1 mol of AL2(SO4)3.

Now we will multiply 342.14g by 1.46.

342.14 * 1.46 = 499.5244 g

Or ... 499.5 g

the answer is true.
