number of molecules is directly proportional to moles


N = kn(moles)


let weight of O2 of M then weigth of N2 is 4M ..


moles of O2 = M/32                              (molar mass of O2 is 32)


moles of N2 = 4M/28                             (molar mass of N2 is 28)


 


N02 = k(M/32)             ..............1


Nn2 = k(4M/28)            .............2


 


dividing both the equations


No2/Nn2 = 7/32
