Question

A gaseous mixture contains 10 gram of hydrogen, 4 gram molecules of oxygen & 28 gram of Nitrogen gas. Calculate molar mass of the mixture.

Answer 1

Answer:

Moles of N

2

=

28

280

=10moles

Assume, moles of CO

2

=x.

So, average molecular mass of mixture =

10+x

10×28+x×44

=36 (given)

So, x=10 moles

Therefore, weight of CO

2

=10×44=440 g you can use this formula
