Answer:
8.3 × 10⁻³ mol Cu
Explanation:
Step 1: Define
Molar Mass of Cu - 63.55 g/mol
Given 0.53 g Cu
Step 2: Use Dimensional Analysis
[tex]0.53 \hspace{3} g \hspace{3} Cu(\frac{1 \hspace{3} mol \hspace{3} Cu}{63.55 \hspace{3} g \hspace{3} Cu} )[/tex] = 0.00834 mol Cu
Step 3: Convert
0.00834 mol Cu = 8.34 × 10⁻³ mol Cu
Step 4: Simplify
We are given 2 sig figs.
8.34 × 10⁻³ mol Cu ≈ 8.3 × 10⁻³ mol Cu
