This follows Boyles law which relates pressure and volume. The law states that pressure is inversely proportional to volume at a constant temperature.
PV = k
where k is a constant.
At two instances ;
P1V1 = P2V2
where parameters for the 1st instance is on the left and parameters for the second instance is on the right.
37.5 kPa x 41.3 L = 13.8 kPa x V2
V2 = 37.5 x 41.3 / 13.8
V2 = 112.23 L
At the new pressure gas will take up a volume of 112.23 L
It evaporates as the CO2 transitions from solid to gas form.
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 /> = 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
