Answer:
0.206 mol H₂O₂
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Reading a Periodic Table
- Using Dimensional Analysis
Explanation:
<u>Step 1: Define</u>
7.00 moles H₂O₂
<u>Step 2: Identify Conversions</u>
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
<u>Step 3: Convert</u>
<u /> = 0.205761 mol H₂O₂
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
0.205761 mol H₂O₂ ≈ 0.206 mol H₂O₂
