  • STP (Standard Conditions for Temperature and Pressure) = 22.4 L per mole at 1 atm, 273 K

Stoichiometry

  • Using Dimensional Analysis

Explanation:

Step 1: Define

[Given]   10.72 mol NH₃ (g)

Step 2: Identify Conversions

[STP] 22.4 L/mol

Step 3: Convert

  1. Set up:                   [tex]\displaystyle 10.72 \ mol \ NH_3(\frac{22.4 \ L \ NH_3}{1 \ mol \ NH_3})[/tex]
  2. Multiply/Divide:     [tex]\displaystyle 240.128 \ L \ NH_3[/tex]

Step 4: Check

Follow sig fig rules and round. We are given 4 sig figs.

240.128 L NH₃ ≈ 240.1 L NH₃
