Hello,
You should first know how to proceed for the solution. From the Ideal Gas equation -
. P V = n R T
. P V = ( given mass / Avg Molar Mass ) R T
. P = ( d R T ) / Avg. Molar Mass
Let the average molecular mass be M
M = ( d R T ) / P
= ( 1.5×0.0821×303×760 ) / 730 ( Use proper Units)
= 38.85
------- Let x mole of CO and (1−x) mole of CO 2 be present
x×28+(1−x)×44=38.85
x=0.3218
Mole % of CO=32.18 and
Mole % of CO 2 =100−32.18=67.82
I hope you find the answer helpful.
Thank you.
