Step 1: Define

[RxN - Balanced] C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

[Given] 150 g O₂

Step 2: Identify Conversions

[RxN] 5 mol O₂ → 3 mol CO₂

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

[PT] Molar Mass of C - 12.01 g/mol

Molar Mass of O₂ - 2(16.00) = 32.00 g/mol

Molar Mass of CO₂ - 12.01 + 2(16.00) = 44.01 g/mol

Step 3: Stoich

Step 4: Check

Follow sig fig rules and round. We are given 2 sig figs.

123.778 g CO₂ ≈ 120 g CO₂

since electrons are negative the answer is neagtaive
