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
Answer
Here,
- Solute is sodium chloride
- Solvent is water .
Now,
Mass of solute = Mass of sodium chloride = 36g
Mass of solvent = Mass of water = 100g
Mass of solution = Mass of solute + Mass of solvent
= 36g + 100g
= 136g
Concentration of solution = (Mass of solute (g)/Mass of solution(g)) × 100%
= (36/136) × 100%
= 9 × 100/34 %
= 26.47 %
