## Question:

What is the mass percent of a solution prepared by dissolving 50.0 grams of NaCl in 150.0 grams of water?

a. 25.0%

b. 33.3%

c. 0.250%

d. 3.00%

e. 40.0%

## Mass Percentage:

The mass percentage of a chemical solution calculates the percentage mass of a solute per gram of the solution. It is calculated as {eq}\text{mass percent}=\dfrac{\text{mass of solute}}{\text{mass of solution}}\times 100 {/eq}.
