Question

151. The molecular weight of O2, and so2, are 32 and 64 respectively. If one litre
of O2, at 15°C and 750mm pressure contains N molecules, the
number
of molecules in two litres of So2, under the same conditions of temperature
and pressure will be:
1) N/2
2) N
3) 2N
4) 4N​

Answer 1

Answer:

2N

Explanation:

equal volume of gas under similar condition of pressure and temperature contain equal no. of molecules

so 1litre SO2 contain N molecules

and 2litre SO2 contain 2N molecules
