Question
Explain the term percentage composition.
Solution
- The percentage composition of a compound is the percentage by weight of each element present in the compound.
- Quantitative determination of the constituent elements by suitable methods provides the percent elemental composition of a compound.
- If the percent total is not 100, the difference is considered as percent oxygen.
- From the percentage composition, the ratio of the atoms of the constituent elements in the molecule is calculated.
