Answer:
ppCO2 = 1.51 atm
total pressure = 3atm
Explanation:
The reaction involved is C + O2 = CO2
I need the number of moles to be able to calculate the partial pressure of CO2 with the general equation of gases.
n = 22.9gCO2 * (1molCO2 / 44gCO2) =0.52mol
T = 20 ° + 273.15K = 293.15K
V = 22.4L
p = nRT / V = (0.52mol * (0.082 atm * L / K * mol) * 293.15K) /22.4L
ppCO2 = 0.56 atm
ppaire = 720torr * (1 atm / 760torr) = 0.95atm
total pressure = ppCO2 + ppaire = 0.56 + 0.95
total pressure =1.51atm
