Question

ii) Weight of a certain volume of gas A is 50 gm and weight of same volume of hydrogen is four
5 gm under similar conditions of temperature and pressure. Find out the vapour density au
molecular weight of gas A. (Atomic weight of C=12, O=16)

Answer 1

Answer:

Answer

Correct option is

A

440 g

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
