Q. If we are asked to use the recorded Wright of copper(II)sulfate pentahydrate to calculate the exact concentration of of an experimentally recorded copper II sulfate in volumetric flask, do we multiply the grams of copper II sulfate by the molar mass to get the molarity  of the copper? Then, do we use the dilution formula to get the concentration. The recorded mass was 2.493 g for 50ml of copper II sulfate stock solution.

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
