Answer:
0.4250 mol MgO
General Formulas and Concepts:
Chemistry - Atomic Structure
- Reading a Periodic Table
- Using Dimensional Analysis
Explanation:
Step 1: Define
17.13 g MgO
Step 2: Identify Conversions
Molar Mass of Mg - 24.31 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of MgO - 24.31 + 16.00 = 40.31 g/mol
Step 3: Convert
[tex]17.13 \ g \ MgO(\frac{1 \ mol \ MgO}{40.31 \ g \ MgO} )[/tex] = 0.424957 mol MgO
Step 4: Check
We are given 4 sig figs. Follow sig fig rules and round.
0.424957 mol MgO ≈ 0.4250 mol MgO
