Mass by mass percentage: Mass percent is a way to express a concentration or to describe the component in a specific mixture.
- The composition of the solution can be represented in a mass percentage that shows the mass of solute present in a given solution quantity.
- The solute quantity is measured in the mass or by moles.
- The mass per cent is defined as the grams of solute per gram of solution for a solution, multiplied by 100 to get the percentage.
- Concentrating a Solution is the amount of solution present in a given quantity (mass or volume) of solution.
Mass % = (mass of solute/mass of solution) x 100
Calculation:
Given:
Solute mass (m) = 50 g, Solvent mass (M) = 350 g
Solution mass = m + M = 50 + 350
Solution mass = 400 g
Mass % = (mass of solute/mass of solution) x 100
Mass % = (50 / 400) × 100
Mass % = 12.5 %
