Explanation:
Step 1: Define
[Given] 2.18 mol Cu
[Solve] grams Cu
Step 2: Identify Conversion
[PT] Molar Mass of Cu - 63.55 g/mol
Step 3: Convert
- [DA] Set up: [tex]\displaystyle 2.18 \ mol \ Cu(\frac{63.55 \ g \ Cu}{1 \ mol \ Cu})[/tex]
- [DA] Multiply [Cancel out units]: [tex]\displaystyle 138.539 \ mol \ Cu[/tex]
Step 4: Check
Follow sig fig rules and round. We are given 3 sig figs.
138.539 g Cu ≈ 139 g Cu
