To make a saturated solution 72g of NaCl is dissolved in 200g of water at 20 degree Celsius. Find its concentration at the same temperature.

Concentration= Mass of solute/ Mass of solution * 100

Mass of solute= 72g

Mass of solution= 72g + 200g

Concentration= 72/272 * 100 = 26.47%

Amount of solute= 72g

Amount of solvent=200g

Amount of solution= amount of solute +amount of solvent =72 +200 = 272g

Concentration= amount of solute/ amount of solution *100 = 72/272 *100 = 26.4%
