Question

question 3
what is the mole ratio of sodium to sodium acetate in nac₂h₃o₂?
2 mol na : 3 mol nac₂h₃o₂
1 mol na : 1 mol nac₂h₃o₂
2 mol na : 1 mol nac₂h₃o₂
1 mol na : 2 mol nac₂h₃o₂

Explanation:

Step1: Analyze the formula

In the formula \( \text{NaC}_2\text{H}_3\text{O}_2 \), there is 1 sodium (\( \text{Na} \)) atom per formula unit of sodium acetate (\( \text{NaC}_2\text{H}_3\text{O}_2 \)).

Step2: Determine the mole ratio

By the definition of mole ratio (based on the formula composition), for every 1 mole of \( \text{Na} \) atoms, there is 1 mole of \( \text{NaC}_2\text{H}_3\text{O}_2 \) formula units.

Answer:

1 mol Na : 1 mol \( \text{NaC}_2\text{H}_3\text{O}_2 \) (the second option)
