Problem: What is the pressure in a 7.50 L flask if 0.15 mol of carbon dioxide (CO 2; molar mass = 44.0 g mol–1 ) is added to 0.33 mol of oxygen (O 2; molar mass = 32.0 g mol –1 )? The temperature of the mixture is 48.0 °C. A. 0.252 atm B. 0.592 atm C. 1.69 atm D. 3.97 atm E. 4.80 atm

We are asked to calculate the pressure of the gas mixture. 

We will use ideal gas equation to calculate for the pressure:

PV=nRT

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