Question

Find the concentration of solution having solubility 30 % containing 40 g of NaCl is dissolved in 250g water.​

Answer 1

Answer: Mass of sodium chloride (Solute) = 40gm

Mass of water (solvent) = 250 gm

Mass of solution = 40+250 = 290gm

Concentration = (Mass of Solute / Mass of Solution) * 100

Concentration = (40/290)*100 = 13.79%

Concentration of solution is 13.79%.
