Most Important Selected Qs for JEE AdvancedChemistrySolutions
Paragraph: Concentration of a solution can be represented in many ways. Some of the important concentration terms are as follows : Molarity of solution = number of moles volume of solution in litre Let a solution is prepared by dissolving w gm of solute of mol . wt . M in V ml water. aligned & Number of moles of solute dissolved = w M & molality = number of moles of solute mass of solvent in gram 1000 & % w / v = mas
