If we know the solute mass and the molarity of a solution, which other concentration unit can we readily determine without needing any other measurement?
A) (w/w)%
B) (w/v)%
C) (v/v)%
D) all of these

Question

Quizplus · Accepted Answer

To determine the (w/v)% concentration, you only need to know the mass of the solute (which is given) and the volume of the solution. Since molarity (mol/L) provides a direct relationship between the amount of solute and the volume of the solution, you can calculate the (w/v)% without additional measurements. The other options require information not directly available from molarity and solute mass alone.
