Question

Hey someone please answer this...

Answer 1

31 mol N₂

General Formulas and Concepts:

Chemistry - Stoichiometry

• Using Dimensional Analysis

Step-by-step explanation:

Step 1: Define

25 mol HCl

Step 2: Identify Conversions

RxN: 4 mol HCl = 5 mol N₂

Step 3: Stoichiometry

`25 \ mol \ HCl((5 \ mol \ N_2)/(4 \ mol \ HCl) )` = 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
