Question
To make a saturated solution, 15 g of sodium chloride is dissolved in 85 g of water at 293 K. Calculate the concentration in terms of mass by mass percentage at this temperature.
Answer: Option A
:
A
Mass of the solute (sodium chloride) = 15 g
Mass of the solvent (water) = 85 g
Mass of the solution = Mass of the solute + Mass of the solvent
= 15 + 85 = 100 g
Concentration (mass by mass percentage) = mass of solutemass of solution×100
= 15 100×100 = 15%
