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?

Answer 1

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.

Answer 2

28.2
