Answer:
344.21 g/mol
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
Explanation:
<u>Step 1: Define</u>
Cr₂(SO₃)₃
<u>Step 2: Identify</u>
Molar Mass of Cr - 52.00 g/mol
Molar Mass of S - 32.07 g/mol
Molar Mass of O - 16.00 g/mol
<u>Step 3: Find</u>
Molar Mass of Cr₂(SO₃)₃ - 2(52.00) + 3(32.07) + 9(16.00) = 344.21 g/mol
The chemical formula depends on the type of acids it is. Acidic rain is a complex mixture of nitrous, nitric, sulfurous and sulfuric acids which all combine to lower the pH.
