Question

equal volumes of methane and ethane are mixed in an empty container at 25 degrees celsius. what fraction of total pressure will be exerted by ethane

Answer 1

P1V1=n1R1T1
P2V2=n2R2T2
R,T,=const
(P1V1)n1 = (P2V2)/n2

n1=n2
when volumes are equal

P1V1=P2V2, when
V1=XV2
P1XV2=P2V2
xP1=P2

ratio of the pressures is inversely
proportional
