Gas problem for chemistry?
A 1.00 L vessel contains 4.26 g of a gas at 1.00 atm and 27.0°C.
(a) Calculate the density of the gas in grams per liter.
g/L
(b) What is the molar mass of the gas? Assume ideal behavior.
g/mol

(a)
density = mass/volume = 4.26/1 = 4.26 g/L
(b)
pV = nRT
n = m/M
pV = mRT/M
M = mRT/(pV)
M = 4.26 x 8.31 x (273 + 27) / (1.01 x 10^5 x 1 x 10^-3)
M = 105.2 g/mol
i have a gas problem to but it is not in chemistry it is in my tank
