Question

what is the concentration (M) of a NaCl solution prepared by dissolving 5.3g of NaCl in sufficient water to give 115mL of solution?

Answer 1

Explanation:

Mass of solute = 5.3g

Volume of solution = 115ml

Mass by volume percentage = Mass of solute/Volume of solution × 100

= 5.3g/115ml × 100

= 4.608g/ml

{ I'm not sure if it's correct or not :) }
