Section 1: Pressure conversions

The density of hydrogen is 9.00 x 10-2 g/L. What will be the mass of 100 liters? What volume will 1.5 x 1023 molecules of oxygen occupy at STP? Measured at STP, 33.6 liters of NO gas represents how many moles? The density of a elemental gas is 1.25 g/L at STP. What is the mass of 1 mole? What could this gas be?
