80.0 liters of oxygen gas is collected over water at 50 degrees celcius. the atomsphereic pressure in the room is 96.00 kPA. what is the partial pressure of oxygen?

ok now first u convert temperature into kelvin and pressure into atm
i am not sure but this could be an approach:
assuming ideal behaviour of oxygen
there for n u can use the relation
n=given mass/molar mass
Oxygen Density is 1.429 g/L
then find p of oxygen gas then as u guys say when can say that is the partial pressure exerted by oxygen in a mixture wud contribute to
absolute pressure=partial pressure
absolute pressure=pressure of gas-atmospheric pressure
i agree wid u evn i done half part but i m just lacking how to cal partial pressure of oxygen from the whole system..
and here if u ll take partial presure it will be of all system not only oxygen @salini
absolute pressure is pressure of gas with respect to atmospheric pressure
i agree but here they are asking for oxygen not Kc ok
that was just my idea i dunno to which extent it is correct
but with the given data this method looked most suitable:)
its.....so simple just use the ideal gas equation PV=NRT
