Nitrogen gas is introduced into a large deflated plastic bag. no gas is allowed to escape, but as more and more nitrogen is added, the bag inflates to accommodate it. the pressure of the gas within the bag remains at 1.00 atm and its temperature remains at room temperature (20.0? c). how many moles n have been introduced into the bag by the time its volume reaches 22.4 l

Use the ideal gas equation: pV = nRT

=> n = RT / pV

R = 0.0821 atm*l / K*mol

T = 20 + 273.15 = 293.15 K

p = 1 atm

V = 22.4 l

=> n = 0.0821 atm*l / K*mol * 293.15K / (1atm * 22.4 l) = 1.07 mole

Answer: 1.07 mole
