Percentage Composition
Percentage composition refers to the relative amounts of different elements or compounds present in a given sample. It is expressed as a percentage and is calculated by dividing the mass of each element or compound by the total mass of the sample and multiplying by 100.
For example, consider a sample of water. The percentage composition would be determined by determining the masses of the different elements (hydrogen and oxygen) present in the water and then calculating their relative proportions.
Key Points:
Percentage composition is a relative measure.
It can be expressed as a percentage.
It is calculated by dividing the mass of each element or compound by the total mass of the sample and multiplying by 100.
Percentage composition provides information about the composition of a substance
