mass/volume percent of the NaCl solution is 38.74%
Explanation:
Mass volume percent of a solutions is defined as:
mass/volume percent = [mass of the solute (g) / volume of the solution (mL)] × 100
For our problem we have:
mass of the solute = 4.78 g of NaCl
volume of the solution = 12.34 mL
mass/volume percent = [4.78 / 12.34] × 100
mass/volume percent = 38.74%
