Answer to Question #175440 in General Chemistry for red
Question #175440
calculate the percent by mass of NaCl solution with molar mass of 58.44g/mole placed in 15.5g of H2O with molar mass of 18.0g/mole.
Expert's answer
We will use 1 g as the value of NaCl mass.
Total mass of the solution = 1 + 15.5 = 16.5 g
The percent by mass of a NaCl
= 1/16.5 × 100
= 6.06%
