Problem

A mixture of CO(g) and O2 (g) in a 1.2 -L container at 1.1×103 K has a total pressure of 2.4 atm . After some time the total pressure falls to 1.9 atm as the result of the formation of CO2.

Find the mass (in grams) of CO2 that forms.

Solution

We have to calculate the mass of CO2 gas in the gas mixture.


We will solve this problem through these steps:

Step 1: Make an ICF chart to calculate the pressure changes that take place.

Step 2: Calculate the number of moles of CO2 using ideal gas equation.

Step 3: Calculate the mass of CO2 using its moles and molar mass.
