Question #16975

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

Expert's answer

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

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
