Question

A
200ml flask
Contains 16mg
O2 & 4mg He at 15 degree Celsius calculate partial
pressure of oxygen and helium in the flask what is the pressure ​

Answer 1

Answer:

by using ideal solution formula

PV=nRT

P200×10^-3=(0.5+1)×0.082×288

p=1.5×0.082×288/200×10^-3

so,

total pressure is 177.12

now partial pressure for O2 is

Po2=x02×total pressure

po2=1/3×177.12

=59.04

by using similar formula

for helium 118.08
