We have two containers with an identical amount of gas in each. One gas is helium, the other is ammonia. Which would you expect to have the higher pressure?

The gas with a higher pressure is  Helium

Calculating the pressure exerted by the gases

Given that temperature and volume is held constant the pressure of a given gas can be calculated as : P = n because for a constant volume and temperature the pressure of a given gas is directly proportional to the number of moles of contained in the gas.

Pressure of Helium

P = n

where n ( number of moles ) = mass of helium / molar mass

                                               = 52 / 4 = 13 moles

Pressure of Ammonia

P = n

where n ( number of moles ) = mass  / molar mass of ammonia

                                                = 73 / 17.03

                                                = 4.29 moles

From the calculations above the gas with a higher pressure is Helium.
