The percent by volume concentration of 35.0 mL of water in 725 mL of an ethanol-water solution should be determined. Concept introduction: The concentration of any solution means the amount of solute present in the specific volume of the solvent. Now the amount of solute present in the solution is expressed by different units like gram, gram-equivalent, gram-mole or mole etc. The amount of solvent to prepare the solution can be expressed in terms of weight or volume. The different unit of expression the concentration of a solution are- percentage strength, normality, molarity, molality, formality, gram per litter, mole fraction, parts per million etc. Volume percent: In every 100 L of the solvent the volume of solute present in any solution is called the mass percent strength of the solution. Like- if in per 100L of any solution 10L pure H 2 SO 4 is present then the volume percent of the solute in the solvent is 10.
