A saturated solution of Ammonium Chloride is dissolved in 100 g of water.
1 answer:
Answer:
10 g
Explanation:
All we need is to read off the solubility curve attached to this answer. The solubility curve is a plot of solubility of a solute against temperature.
By reading off the solubility curve, we can know the mass of precipitate that crystallizes out as the solution is cooled from 50°C to 30°C.
From the solubility curve;
Mass of Ammonium Chloride dissolved at 50°C = 50 g
Mass of Ammonium Chloride dissolve at 30°C = 40 g
Hence;
Mass of precipitate formed = 50 g - 40 g
Mass of precipitate formed = 10 g
