Answer:
31 mol N₂
General Formulas and Concepts:
Chemistry - Stoichiometry
- Using Dimensional Analysis
Explanation:
Step 1: Define
25 mol HCl
Step 2: Identify Conversions
RxN: 4 mol HCl = 5 mol N₂
Step 3: Stoichiometry
[tex]25 \ mol \ HCl(\frac{5 \ mol \ N_2}{4 \ mol \ HCl} )[/tex] = 31.25 mol N₂
Step 4: Check
We are given 2 sig figs. Follow sig fig rules and round.
31.25 mol N₂ ≈ 31 mol N₂
