To make a saturated solution , 36 g of sodium chloride is dissolved in 100g of water at 293 K. Find its concentration at this temperature
Mass of solute (sodium chloride) =36g
Mass of solvent (water) =100g
Mass of solution = Mass of Solute + Mass of solvent
= 36g +100g = 136g
Concentration =Mass of solute /Mass of solution×100
=36/136×100=26.47%
