The mass fraction is a measure used in chemistry and other scientific fields to express the proportion of one substance (the “component”) in a mixture relative to the total mass of the mixture. It is a dimensionless quantity expressed as a ratio or percentage.
Mathematically, the mass fraction () of a component in a mixture is defined as:
Where:
- mass of component in (Kg).
- total mass of mixture in (Kg).
This formula calculates the ratio of the mass of the component to the total mass of the mixture. The result is typically expressed as a decimal, fraction, or percentage.
