Given - Gases whose partial pressure has to be equal - sulphur dioxide and nitrogen monoxide.
Find - Mass ratio of sulphur dioxide and nitrogen monoxide for their partial pressure to be equal.
Solution - Partial pressure is directly proportional to number of moles, keeping other values constant. Hence, number of moles of sulphur dioxide to nitrogen monoxide will be calculated.
Mass (SO2)/Molecular weight (SO2) = Mass (NO)/ Molecular weight (NO)
Mass (SO2)/Mass (NO) = Molecular weight (SO2)/ Molecular weight (NO)
Mass (SO2)/Mass (NO) = 64/30
Mass (SO2)/Mass (NO) = 32/15.
Hence, 32 : 15 is the mass ratio of SO2 to NO so that their partial pressure in a container becomes equal.
