Question

write short note unit of express concentration of solution​

Answer 1

It can be expressed in several ways: molarity (moles of solute per liter of solution); mole fraction, the ratio of the number of moles of solute to the total number of moles of substances present; mass percentage, the ratio of the mass of the solute to the mass of the solution times 100; parts per thousand (ppt), grams

Answer 2

Unit of express concentration of solution can be given in 5 ways.

Explanation:

• concentration of solution is defined as the amount of solute is present in the solution.
• Percentage of weight = weight of the solute is divided by weight of the solution and it is unitless.
• Percentage of volume = volume of the solute is divided by volume of the solution and it is unitless.
• Weight by volume = weight divided by volume percent and its unit is g/l.
• Mole fraction = number of moles by total number of moles and it is unitless.
• Parts per million = mass of the solute by mass of solution × $10^{6}$ and its unit is ppm.
