A solution is prepared by dissolving 8.75 grams of sodium chloride in enough volume of water to produce 112.0 grams of the NaCl

ICE Princess25 [194]

Answer : The percent by mass of the solution is 7.81 %

Explanation : Given,

Mass of NaCl = 8.75 g

Mass of solution = 112.0 g

Now we have to determine the percent by mass of the solution.

$\text{Mass percent}=\frac{\text{Mass of NaCl}}{\text{Mass of solution}}\times 100$

Putting values in above equation, we get:

$\text{Mass percent}=\frac{8.75g}{112.0g}\times 100=7.81\%$

Therefore, the percent by mass of the solution is 7.81 %
