What is mass concentration:
- Like molar concentration, molality, and mass fraction, mass concentration is a quantity used to determine the concentration of a solute in a solution. It is the proportion of a solute's mass in a solution to that solution's volume. It reveals how much of a solute there is in a certain volume of solution.
- The fluctuation in solution volume caused mostly by thermal expansion affects mass concentration. The following dependence holds for short temperature intervals.
- Kilograms per cubic metre, or kg/m3, is the SI measure for mass concentration. The units of this are mg/mL and g/L. Similar to g/dL (gram/decilitre), g/(100 mL) is another frequently used unit.
How to calculate mass concentration:
- Rearranging the equation for concentration allows the mass of solute to be calculated:
- mass of solute in g = concentration in g/dm3 × volume in dm3.
