The gas with a higher pressure is <u>Helium </u>
<h3 /><h3>Calculating the pressure exerted by the gases</h3>
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.
<u>Pressure of </u><u>Helium </u>
P = n
where n ( number of moles ) = mass of helium / molar mass
= 52 / 4 = 13 moles
<u>Pressure of</u><u> Ammonia </u>
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.
