Question

N2 and CO2 have same molar formula.
How verify ​

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

Explanation:

We have,

PV=nRT

P, R, T are same, hence we get
