Question
What does the percentage composition of a substance define?
- Percent of the molecule
- Percent of the compound only
- Percent of elements present in molecule
- Percent of atoms present in element
Hint:
The ratio of the amount of each element to the total amount of individual elements present
The correct answer is: Percent of elements present in molecule
The percentage composition of a given compound is defined as the ratio of the amount of each element to the total amount of individual elements present in the compound multiplied by 100. Here, the quantity is measured in terms of grams of the elements present.
The percentage composition of a substance define percent of elements present in molecule.
