Question

the chemical formula for water is HO. This means that one water molecule is made of toms of hydrogen and oxygen in the ratio H: 0= 2:1. how many atoms of hydrogen and how many atoms of oxygen are present in 42 olecules of HO? ​

Answer 1

Answer:

Refer to Table 3.4 for ratio by mass of atoms present in molecules and Table 3.2 for atomic masses of elements. Find the ratio by number of the atoms of elements in the molecules of compounds given in Table 3.4. Thus, the ratio by number of atoms for water is H:O = 2:1. 3.3.
