Question

One type of gas used in is a 50%/50% module (by volume) of (N_2O) and (O_2) which can too premised and kept in a cylinder for faster use Because these two gases don't below 2000 psi at typical room temperatures they form a homogenous single gas phases which can be considered an ideal gas if the temperature drops below 6 degree C however N_2O may begin to condense out of the gas phase. Then any gas removed from the cylinder will be nearly pure O_2: as the cylinder empress, the proportion of O_2 will What volume of at 20 degree C and 50 psi

Explanation / Answer

P = 50 psi = 50*3.4 atm = 170atm
m = 3.5Kg = 3.5*1000 = 3500gm
molar mass m = 44
T             = 20C = 20 + 273 = 293K
Pv = nRT
no of moles n = 3500/44 = 79.54
V = nRT/P

   = 79.54*0.0821*293/170
   = 11.25L = 0.01125m^3 >>> answer
