3.81 moles HC2H3O2 to grams

229 g HC₂H₃O₂

General Formulas and Concepts:

Explanation:

Step 1: Define

3.81 mol HC₂H₃O₂ (C₂H₄O₂)

Step 2: Define conversions

Molar Mass of C - 12.01 g/mol

Molar Mass of H - 1.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of C₂H₄O₂ - 2(12.01) + 4(1.01) + 2(16.00) = 60.06 g/mol

Step 3: Dimensional Analysis

= 228.829 g HC₂H₃O₂

Step 4: Simplify

We are given 3 sig figs.

228.829 g HC₂H₃O₂ ≈ 229 g HC₂H₃O₂
