How many moles of gas does the cylinder contain?

42.8 psi = 2.91 atm
assuming both are absolute
n = PV/RT = (2.91)(11) / (0.08206)(273.16+30) = _____ mol
Ideal gas law
PV = nRT
n = number of moles
R = gas constant = 0.08206 (atm∙L)/(mol∙K)
T = temperature in kelvins
P = absolute pressure in atm, kPa, bar, torr
V = volume in liters
