# 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.

###### FREE Expert 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.
