A solution of ammonia and water contains 2.90×1025 water molecules and 9.00×1024 ammonia molecules. How many total hydrogen atoms are in this solution?
any help would be great.

• Chemistry -

There are 2*2.9-E25 H atoms in the H2O.
There are 3*9.00E24 H atoms in the NH3.
Total = the sume of the two.
