Answer:
0.206 mol H₂O₂
General Formulas and Concepts:
Chemistry - Atomic Structure
- Reading a Periodic Table
- Using Dimensional Analysis
Explanation:
Step 1: Define
7.00 moles H₂O₂
Step 2: Identify Conversions
Molar Mass of H - 1.01 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of H₂O₂ - 2(1.01) + 2(16.00) = 34.02 g/mol
Step 3: Convert
[tex]7.00 \ g \ H_2O_2(\frac{1 \ mol \ H_2O_2}{34.02 \ g \ H_2O_2} )[/tex] = 0.205761 mol H₂O₂
Step 4: Check
We are given 3 sig figs. Follow sig fig rules and round.
0.205761 mol H₂O₂ ≈ 0.206 mol H₂O₂
