gizmo_the_mogwai [7]

Answer:

12.9 L Kr

General Formulas and Concepts:

<u>Chemistry - Gas Laws</u>

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

Explanation:

<u>Step 1: Define</u>

0.575 mol Kr

<u>Step 2: Identify Conversions</u>

1 mol= 22.4 L at STP

<u>Step 3: Convert</u>

<u />0.575 \ mol \ Kr(\frac{22.4 \ L \ Kr}{1 \ mol \ Kr} ) = 12.88 L Kr

<u>Step 4: Check</u>

<em>We are given 3 sig figs. Follow sig fig rules and round.</em>

12.88 L Kr ≈ 12.9 L Kr
