(b) what is the volume percent % (v/v) of an alcohol solution made by dissolving 135 ml of isopropyl alcohol in 745 ml of water? (assume that volumes are additive.)

Respuesta :

volume percentage is the percentage of volume of interested compound from the whole volume of the solution.
volume percentage of isopropyl alcohol can be calculated as follows;
volume percentage (v/v%) = volume of alcohol/ total volume of solution x 100%
total volume = 135 + 745 = 880 mL
substituting the values ,
v/v % of alcohol = 135 mL / 880 mL x 100 %
answer = 15.34 %
