General Formulas and Concepts:

Chemistry - Atomic Structure

Explanation:

Step 1: Define

Cr₂(SO₃)₃

Step 2: Identify

Molar Mass of Cr - 52.00 g/mol

Molar Mass of S - 32.07 g/mol

Molar Mass of O - 16.00 g/mol

Step 3: Find

Molar Mass of Cr₂(SO₃)₃ - 2(52.00) + 3(32.07) + 9(16.00) = 344.21 g/mol
