a solution of ammonia and water contains 1.70x10^25 water molecules and 5.90x10^24 ammonia molecules. how many total hydrogen atoms are in the solutions?

will get back to you ...............

6.022* 10^23 molecules of water contains 2* 6.022* 10^23 hydrogen atoms

So 1.70x10^25 molecules of water contains  2* 1.70 x10^25 hydrogen atoms

Similarly 6.022* 10^23 molecules of ammonia contains 3* 6.022* 10^23 hydrogen atoms

So 5.90x10^24 molecules of ammonia contains 3* 5.90x10^24  hydrogen atoms

Total no: of hydrogen atoms = (2* 1.70 x10^25) + (3* 5.90x10^24)

= 51.7 * 10^24 atoms

Please let me know if you have any questions and best me if you are satisfactory.
