Ans.1)  centration is a measure of amount of solute in solvent .

It can be expressed in various ways.

1.       Mass percentage (mass of solute * 100 / mass of solution)

2.       Volume percentage (volume  of solute * 100 / Volume of solution)

3.       Mass-volume percentage (mass of solute in gram * 100 / Volume of solution in mL)

4.       Molarity (M),  (M = No. of moles of solute / Volume of solution in liter)

5.       Molality (m), (m = No. of moles of solute / Mass of solvent in Kg)

6.       Normality (N), (N = No. of equivalents  of solute / Volume of solution in liter)

7.       Formaility (F), (F = Moles of undissolved solute / Volume of Solution in liter

8.       Mole fraction (÷),  (÷  = moles of solute/ moles of solvent )

9.       Parts per million (ppm), (ppm = mg of solute / Kg of solution )
