How many atoms of sodium are in 3.80 mol of sodium, Na?
vova2212 [387]

Answer:

2.29 × 10²⁴ atoms Na

Explanation:

Step 1: Define

Avagadro's Number: 6.02 × 10²³ atoms, molecules, formula units, etc.

Step 2: Stoichiometry

3.80 \hspace{3} mol \hspace{3} Na(\frac{6.02(10)^{23} \hspace{3} atoms \hspace{3} Na}{1 \hspace{3} mol \hspace{3} Na} ) = 2.2876 × 10²⁴ atoms Na

Step 3: Simplify

We have 3 sig figs.

2.2876 × 10²⁴ atoms Na ≈ 2.29 × 10²⁴ atoms Na

Why do atoms want 8 valence electrons?
Neporo4naja [7]

Answer:
