Step 1: Define

[Given] 2.16 moles SO₂

[Solve] grams (mass) SO₂

Step 2: Identify Conversions

[PT] Molar Mass of S - 32.07 g/mol

[PT] Molar Mass of O - 16.00 g/mol

Molar Mass of SO₂ - 32.07 + 2(16.00) = 64.07 g/mol

Step 3: Convert

Step 4: Check

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

138.391 g SO₂ ≈ 138 g SO₂
