We are asked to calculate the pressure of the gas mixture.
We will use ideal gas equation to calculate for the pressure:
P = pressure, atm
V = volume, L
n = moles, mol
R = gas constant = 0.08206 (L·atm)/(mol·K)
T = temperature, K
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
