Explanation:
Step 1: Define
50.3 mol KCl (Potassium chloride)
Step 2: Identify Conversions
Avogadro's Number
Step 3: Convert
[tex]\displaystyle 50.3 \ mol \ KCl(\frac{6.022 \cdot 10^{23} \ formula \ units \ KCl}{1 \ mol \ KCl} )[/tex] = 3.02907 × 10²⁵ formula units KCl
Step 4: Check
We are given 3 sig figs. Follow sig fig rules and round.
3.02907 × 10²⁵ formula units KCl ≈ 3.03 × 10²⁵ formula units KCl
