ASSIGNMENT
solution. Sodium chloride was isolated from a solution of unknown concentration. The
Sodium chloride (solute) was dissolved in water (solvent) to
make a sodium chloride
volume of the solution
was 9.50 mL, and the
mass of the solution was 9.98 g. The final
mass
of the sodium chloride (NaCl) was 1.0054 g.
1. Calculate the density of the sodium chloride solution.
2. Calculate the percent by mass concentration of the sodium chloride solution.
3. Calculate the molar concentration (molarity) of the sodium chloride solution.
