Step 1: Define

5.26 mol Fe₂(SO₄)₃

Step 2: Identify Conversions

Molar Mass of Fe - 55.85 g/mol

Molar Mass of S - 32.07 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of Fe₂(SO₄)₃ - 2(55.85) + 3(32.07) + 12(16.00) = 399.91 g/mol

Step 3: Convert

Step 4: Check

Follow sig fig rules and round. We are given 3 sig figs.

2103.53 g Fe₂(SO₄)₃ ≈ 2100 g Fe₂(SO₄)₃
