THanks a  lot astar :) U rock!!

astarmathsandphysics:
pV= K

d=m/V so dV=m so V=m/d so pm/d =K so p/d=K/m =C another constant.
Not the mass m of the gass is fixed so now pressure/density=constant

ok few more please

For 10 min each, at 27 degrees celsius,from 2 identical holes,nitrogen and an unknown gas are leaked into a common vessel of 3 litre capacity. The resulting pressure is 4.18 bar and mixture contains 0.4 mole of nitrogen. WHat is the  molar mass of the unknown gas?
