We’re being asked to calculate the mass of carbon dioxide in a 10.0 L container at 25°C. 

The container consists of a mixture of oxygen gas (O2), nitrogen gas, and carbon dioxide (CO2).


We’re going to calculate the mass of carbon dioxide in grams using the following steps:


Step 1. Calculate the total number of moles of gas present in the container using the ideal gas equation.

PV=nRT

P = pressure, atm
V = volume, L
n = moles, mol
R = gas constant = 0.08206 (L·atm)/(mol·K)
T = temperature, K

Step 2. Calculate the number of moles of carbon dioxide.
Step 3. Calculate the mass of carbon dioxide.
