Find the ratio by number of the atoms of elements in the molecules of water, ammonia and carbon dioxide. |
Answer» SOLUTION :The ratio by NUMBER of ATOMS for a WATER molecule can be found as follows:  The ratio by number of atoms for water is H:O = 2:1. `to` The ratio by number of atoms for an ammonia molecule can be found as follows:  `to` Thus, for ammonia, the ratio of atoms is N:H= 1:3 `to` The ratio by number of atoms for carbon dioxide molecule can be found as follows:  `to` Thus, for carbon dioxide, the ratio of atoms is С:O=1:2. |
