Answer:
344.21 g/mol
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
