Question

Mass by mass percentage = _______________________.
1. (mass of solute/mass of solution) x 100
2. (mass of solution/mass of solute) x 100.
3. (mass of solute/volume of solution) x 100.
4. (volume of solute/mass of solution) x 100.

Answer 1

Correct Answer - Option 1 : (mass of solute/mass of solution) x 100

Mass by mass percentage = (mass of solute/mass of solution) x 100.

• Mass per cent 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.
