Problem

What is the percent CdSO4 by mass in a 1.0 molal aqueous CdSO4 solution?

A. 0.10 %
B. 20.8 %
C. 17.2 %
D. 24.4 %
E. 0.001%

Solution

We’re being asked to calculate the mass percent of CdSO4 in a 1.0 molal aqueous CdSO4 solution.

Aqueous solution means that water is the solvent, hence CdSO4 is the solute.


Mass or weight percent (% by mass) is the percentage of a given element or compound within a solution. 

The equation used to calculate for mass percent is shown below:

mass percent = mass componenttotal mass×100
