We are given initially with 1.2 x 1024 molecules of water, added further with 5.0 moles of water. we are asked to determine the total number of molecules of water after the addition. We just convert the number of moles to number of molecules. 5 moles of water is equal to 3.011x 10^24 molecules. The total number is that we add the initial and the additional, equivalent to 4.211 x10^24 molecules.
