Question

A gaseous mixture contain 80% cH4 20%H2 at760 mm pressure &27 degrees. What is density of mixture

Answer 1

Explanation:

Answer

no. of moles of nitrogen gas =

28

56

=2

no . of moles of carbon-dioxide gas =

44

44

=1

no. of moles of methane =

16

16

=1

Total no. of moles in the mixture = 4

Thus, mole fraction of methane =X
