What is the percent by mass of sodium chloride in a solution of 44G of NaCl dissolved in 756GH2O

Hey there!

First find the total mass of the solution.

756 + 44 = 800 grams

Then, find the percent that 44 grams is of 800 grams.

44 ÷ 800 = 0.055

0.055 x 100 = 5.5%

The percent of the solution that is NaCl is 5.5%.

Hope this helps!
