Q.How can we determine Concentrations of Solutions?
Ans.
The concentration of a solution is the quantitative expression of the amount of solute dissolved in the solution.
It is common to measure concentration by the number of moles of solute dissolved in one liter of solution. This is known as the molarity of a solution and is abbreviated M. For example, the concentration of a solution of 3 moles of NaCl in one liter of solution is written 3M. The concentration of 3M is read as "3 molar."
Brackets can be used to denote concentration. For example, the concentration of Na+ in a solution can be written [Na+].
