Given 500. cm3 of methane gas at 2.5 atm and 20 oC. What is the volume of the gas at STP? =
1.2 x 103 cm3
What pressure is exerted by 2.0 moles of a gas in a 500 cm3 container at 25 oC? = 98 atm
Two hundred cubic centimeters of a gas are collected by water displacement. The conditions at
time are 1.1 atm and 30 oC. The vapor pressure of water at 30 oC is 23.4 mm Hg. What would be
the pressure of the dry gas? = 817 mm Hg (or 1.1 atm if you convert water pressure to atm and
account for SF)
