Answer:
0.9401 mol H₂O
General Formulas and Concepts:
Chemistry - Atomic Structure
- Reading a Periodic Table
- Using Dimensional Analysis
Explanation:
Step 1: Define
16.94 g H₂O
Step 2: Identify Conversions
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
Step 3: Convert
[tex]16.94 \ g \ H_2O(\frac{1 \ mol \ H_2O}{18.02 \ g \ H_2O} )[/tex] = 0.940067 mol H₂O
Step 4: Check
We are given 4 sig figs. Follow sig fig rules and round.
0.940067 mol H₂O ≈ 0.9401 mol H₂O
