Explanation:
No. Of molecules = no. of moles*avogadro number(N)
Number of moles = gram molecular weight of molecule/Given weight
(G.M.W/given weight)
1) G. M. W = 2*14 = 28g
given weight =7g
No.of moles=28/7
=4
No. Of molecules = 4*N
2)G.M.W=2*1=2g
Given weight = 2g
No.of moles= 2/2
=1
No. Of molecules = 1*N
3)G.M.W = 2*8 = 16g
Given weight =8g
No.of moles = 16/8
=2
No. Of molecules = 2*N
4) G.M.W = 46g
Given weight = 20g
No.of moles= 46/20
No. Of molecules = 46/20*N
Hence 7g of N2 consists of most no. of molecules.
Hope it helps:)
