How many moles of CO2 should be placed in a 250 ml container at -24 Celsius to produce a pressure of 95 kPa?

0.011 mol CO₂

General Formulas and Concepts:

Chemistry - Gas Laws

Combined Gas Law: PV = nRT

Temperature Conversion: K = °C + 273.15

Explanation:

Step 1: Define

250 mL

-24°C

95 kPa

Step 2: Identify Conversions

Temp Conversion

1000 mL = 1 L

Step 3: Convert

= 0.25 L

-24°C + 273.15 = 249.15 K

Step 4: Find Moles

Step 5: Check

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

0.011465 mol CO₂ ≈ 0.011 mol CO₂
