which of the following contains maximum number of atoms and why? (a) 4g of H2 (b) 16g of O2 (c) 28g of N2 (d) 18g of H2O

Answered by admin @ 10/08/2021

Answer:

Let's convert given data into no. of moles first

By formula n=m/M

a) 4g of H2

No. of moles (n) = 4/2

(b) 16g of O2

No. of moles (n) = 16/32

No. of moles (n) = 28/28

(d) 18g of H2O

No. of moles (n) = 18/18

Clearly, 4 g of Hydrogen contains maximum number of atoms.

So, correct option is (a)
