To make a saturated solution, 36 g of sodium chloride is dissolved in 100 g of water at 293 K. Find its concentration at this temperature.

NCERT Class 9th Science Ch 2 Is Matter Around Us Pure


Mass of solute(sodium chloride) = 36g
mass of solvent (water) = 100g
mass of solution = mass of solute+mass of solvent
concentration= \frac{mass of solute}{mass of solvent}*100  \frac{36g}{100g}*100 = 26.47%
