Gram Molecular weight of H20 is 18 g
To calculate the number of molecules in 27g if water , first calculate the number of moles i.e; 27/18 = 1.5 moles
Now to calculate the number of molecules we multiply it with the avagadro’s number providing us with the value
= 1.5 * 6.022*10^23
9.033*10^23 molecules
