ammonia and water solution has 1.70x10^25 h2o molecules and 5.90x10^24 ammonia, how many hydrogen are there in NH3 molecules?
Can u please check if d question is correct?
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
