Which of the following has the maximum number of atoms and how?

a) 18g of O2 b)18g of H2Oc) 18g of CO2d) 18g of CH4

Answered by admin @ 10/08/2021

The greater the no.of moles of the substance , the higher the number of molecules or atoms of that substance.

So, we'll check which substance is having the most number of moles.

a) 18 g of O2
no of moles = 18/2*16 = 18/32 = 9/16

b) 18 g of H2O
no of moles = 18/18 = 1 mole

c) 18 g of CO2
no. of mole = 18/44 = 9/22

d) 18 g of CH4
no. of mole = 18/16 = 9/8 = 1.125

So, CH4 has the most number of moles and thus most number of molecules.
