first you divide by avagadro's number to get number of moles. 3.41x10^26 / 6.022x10^23 = 566.25 moles The molecular mass of water is 18. moles is mass/molecular weight of sor moles by the mass is the weight. 566.25*18 is 10192.63 g. This is 10.193 kg Are you sure your molecule count was not exponentially lower?
