    Answer:

    81 L gas

    General Formulas and Concepts:

    Ideal Gas Law

    • 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] 3.6 mols gas at STP

    [Solve] volume (L) of gas

    Step 2: Convert

    1. [DA] Set up:                                                                                                       \displaystyle 3.6 \ mol \ gas(\frac{22.4 \ L \ gas}{1 \ mol \ gas \ at \ STP})
    2. [DA] Multiply [Cancel out units]:                                                                      \displaystyle 80.64 \ L \ gas

    Step 3: Check

    Follow sig fig rules and round. We are given 2 sig figs.

    80.64 L gas ≈ 81 L gas
