volume of 222 mL at a? (1). What is the pressure in millimeters of mercury of 0.0140 mole of helium gas with a volume of 222 mL at a temperature of 30 degree Celsius?
(2). How many moles of gas must be forced into a 4.8 L tire to give it a gauge pressure of 33.6 psi at 30 degree Celsius? The gauge pressure is relative to atmospheric pressure. Assume that atmospheric pressure is 14.7 psi so that the total pressure in the tire is 48.3 psi.
Express your answer using two significant figures.
