Moles=mass/molar  mass  of  water.  the molar  mass of   water  is  found  to    be  18g  which   is  calculated    adding  the  molar  mass  of  hydrogen  plus  that  of oxygen  that  is(2x 16)+(1 x2)=18g/mol
  convert  Kg    to  grams that   is 1.8kg x  1000=1800g

moles  is  therefore 1800g /18g/mol=100 mol
