1.	A vessel is filled with a mixture of oxygen and nitrogen . At what ratio of partial pressures will the mass of the gases be indentical ?
Answer» Solution :`PV=nRT=(W)/(M)RT` `P_(O_(2))V=(w_(O_(2)))/(32)xxRT` `P_(N_(2))V=(w_(N_(2)))/(28)xxRT` `:. "" (P_(O_(2)))/(P_(N_(2)))=(w_(O_(2)))/(32)xx(28)/(w_(N_(2)))=(28)/(32)""(because w_(O_(2))=w_(N_(2)))` `=(7)/(8)=7:8`
