What would be the pressure (in atmospheres) exerted by 0.75 moles of an ideal gas, if the gas filled a 40.5 liter container at a temperature of 19 degrees Celsius? (The ideal gas constant is 0.0821 L•atm/mol•K.)

10 Points for correct answer.

PV = nRT

P = nRT / V = (0.75 mol) x ( 0.0821 L•atm/mol•K) x (19 + 273 K) / (40.5 L) = 0.44 atm
