  • Using Dimensional Analysis
  • Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.

Step-by-step explanation:

Step 1: Define

4 mol Na₃P

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

[tex]\displaystyle 4 \ mol \ Na_3P(\frac{6.022 \cdot 10^{23} \ atoms \ Na_3P}{1 \ mol \ Na_3P} )[/tex] = 2.4088 × 10²⁴ atoms Na₃P

Step 4: Check

We are given 1 sig fig. Follow sig fig rules and round.

2.4088 × 10²⁴ atoms Na₃P ≈ 2 × 10²⁴ atoms Na₃P
