A solution of ammonia and water contains 2.70×1025 water molecules and 7.60×1024 ammonia molecules. How many total hydrogen atoms are in this solution?

  • chemistry -

    H atoms in water = 2.70E25 x (2 atoms H/1 molecule H2O)?

    H atoms in NH3 = 7.60E24 x (3 atoms H/1 molecule NH3) = ?

    The sum will give you the total numbr of H atoms.
