a solution has a concentration of 0.52 m KBr and a volume of 0.020 l. it is then diluted to a concentration of 0.13 m. So the new volume will be 80 mL.
The term "solution" refers to a certain kind of homogenous mixture made up of two or more substances. A solute, or substance that is dissolved in a solvent, is one of the components of such a mixture. On a scale where chemical polarity has an impact, a solution is mixing, leading to interactions that are unique to solvation. When the solvent comprises a greater portion of the mixture, as is frequently the case, the solution typically has the condition of the solvent. The concentration, which is a gauge of how much solute is present in a given volume of solution or solvent, is one crucial parameter of a solution. In cases where water serves as one of the solvents, the phrase "aqueous solution" is employed.
By using the law of equivalence:-
M1 V1 = M2 V2
known = unknown
0.52 M x 20mL= 0.13 x V2
V2 = 80 mL
so the new volume will be 80 mL.
