Question

Exercise C Calculating volumelvolume % Concentration (1 pt per answer, 10 total) Complete the following table by calculating the volume/volume % for the following solutions. The volume/volume % is the volume of the solute in mL divided by the volume of the solution in mL x 100. The volume of the solution is equal to the volume solvent plus the volume of solute. Fill in all of the empty spaces. The volume of the solute and the solvent must be in the same units. Volume of solution Volume/volume % Volume solute 85.0 mL 55 mL Volume solvent 175mL 240. mL 750. mL 34.% 1.200 Liters 95 mL 64 mL 45%
