Use the Ideal Gas Law equation to calculate the unknown quantity in the following measurement. The GFM is the molar mass of the substance.
Pressure = 0.65 Atm
Volume=4745.2 L
mass=12080 grams
GFM=?? g/mole
Temp.- 249 degrees Kelvin
If you understand this problem, please show me the formula that you used. I'm not sure how to set it up.
Thanks

pV=nRT
(0.65 atm)(4745.2 L)=n(0.08206 L-atm/mol-K)(249 K)
n = 150.95 mol
12080 g / 150.95 mol = 80.02 g/mol

pV=nRT
R=0.08206
n=pV/RT = 0.65(4745.2) / 0.08206(249)
n= 3084.4 / 20.4 = 150.9 moles
12080 g ( GFM g/mol)=150.9 moles
GFM = 80.05 g/mol
