Answer

Explanation:

Step1: Analyze the chemical - equation ratio

From the equation (2Na + H_2O\rightarrow2NaOH + H_2), 2 moles of Na react with 1 mole of (H_2O).

Step2: Use Avogadro's number

1 mole of any substance contains (6.02\times10^{23}) entities. Since 2 moles of Na react with 1 mole of (H_2O), the number of Na atoms (n = 2\times6.02\times10^{23}=1.204\times10^{24}).

Answer:

B. (1.204\times 10^{24})
