Question

The molecular weight of O2 and SO2 are 32 and 64 respectively. If one litre of O2 at STP contains N molecules, the number of molecules in two litres of SO2 at STP. (a) N/2 (b) N (c) 2N (d) 4N

Answer 1

Answer:

2N

Explanation:

according to avogadros law equal volume of gases at similar condition of pressure and temperature contain equal no. of molecules

so 1litre SO2 contain N molecules

and 2litre SO2 contain 2N molecules
