Question

1. if a solution has a mass percent of 15%, what does this mean?

a. 15% of the solution is solvent
b. 15% of the solvent is dissolved
c. 15% of the solute’s mass is solvent
d. 15% of the solution’s mass is solute

Explanation:

Mass percent of a solute in a solution is defined as the ratio of the mass of the solute to the total mass of the solution, multiplied by 100. A 15% mass percent means 15% of the total solution mass is the solute, while the remaining 85% is the solvent.

Answer:

d. 15% of the solution's mass is solute
