Now, we know that in 1 mol of anything there are this many molecules. So to find the number of molecules in one point eleven moles of water we simply multiply this number by Avogastro's number. So we get 6.22 times ten to the 23 atoms. Or actually, in our case, this should be molecules. Molecules per mole, times one point eleven moles of water. So the moles cancel and we're left with 6.68 times tens of 23 molecules of water.
