Methane is formed in landfills by the action of certain bacteria on buried organic matter. If a sample of methane collected from a landfill has a volume of 500. mL at 744. torr and 22. °C, how many grams of methane are in the sample?

First, get the number of moles (n) by using the ideal gas law
n = PV/(RT)
R = 82.06 cm^3*atm/(mole*K)
V = 500 cm^3
P = 744/760 = 0.9789 atm
T = 295 K
n = 0.0202 moles
Then multipy n by the molecular weight(16 g/mole)
n = PV/(RT)
R = 82.06 cm^3*atm/(mole*K)
V = 500 cm^3
P = 744/760 = 0.9789 atm
T = 295 K
n = 0.0202 moles
Then multipy n by the molecular weight(16 g/mole)
