a. Total pressure = pH2O + pgas. Substitute and solve for pN2(the gas).
b. Then PV = nRT.
P is pN2. You know V, R and T. Solve for n.
A student designs an experiment to determine the molar volume of nitrogen gas using a barometer, thermometer, table of vapor pressures of water, rubber tubing, a container that dispenses nitrogen gas, and a gas collection tube.
a) determine the partial pressure of the nitrogen gas in the collection tube if the total pressure is 1.000 atm and the partial pressure of water is 23.79 torr at 25 degrees C.
b) determine the number of moles of nitrogen gas collected in the tube if the volume of gas collected was 0.0591 L at 25 degrees C
