Answer:
0.19 mol H₂O
General Formulas and Concepts:
<u>Chem</u>
- Reading a Periodic Table
- Using Dimensional Analysis
Explanation:
<u>Step 1: Define</u>
Given: 3.5 g H₂O from RxN
<u>Step 2: Define conversions</u>
Molar Mass of H - 1.01 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of H₂O - 2(1.01) + 16.00 = 18.02 g/mol
<u>Step 3: Convert</u>
<u /> = 0.194229 mol H₂O
<u>Step 4: Check</u>
<em>We are given 2 sig figs. Follow sig fig rules.</em>
0.194229 mol H₂O ≈ 0.19 mol H₂O
