D. (mass/mass) X 100 is a percentage concentration of the solution.
The concentration of a solution:
- Solution concentration is a measurement of how much solute has dissolved in a particular amount of solvent or solution.
- A solution that contains a substantial amount of dissolved solute is said to be concentrated.
- A solution that contains just a little quantity of dissolved solute is said to be diluted.
- By examining the solution's concentration, you may determine how much solute has been dissolved in the solvent.
- If you add 1 teaspoon of salt to 2 cups of water, for example, the concentration would be 1 teaspoon of salt per 2 cups of water.
Different ways of expressing the concentration of a solution:
- Concentration in Parts Per Million (ppm)
- Mass Percentage (w/w)
- Volume Percentage (V/V)
- Mass by Volume Percentage (w/V)
- Molarity (M)
- Molality (m)
- Normality
- Formality
- Mole Fraction
