Question

To make a saturated solution, 70 g of sodium chloride is dissolved in 140 g of water at 293 K. Find its concentration at this temperature.

Answer 1

Answer:33.33%

Explanation: Concentration of solution= (Mass of solute / Mass of solution) *100%

Mass of solute= 70 g

Mass of solution = Mass of solute+ Mass of solvent = 70+ 140= 210g

Concentration= 70/210 *100% = 33.33%
