Explanation Of Percent Concentration

May 17, 2011 · If the percent concentration of a material in solution is expressed as ‘v/v’, this is known as the volume concentration of the solute in solution This expression is commonly used when the solute is measured by volume before being added to the solution To accurately calculate the volume concentration, the weight per gallon of
