Answer:
a) Mass of solid W crystallized out 0°C is 141.564 g
b) 91.92% is the percent recovery.
Explanation:
The solubility of solid W in water at 100°C = 21.3 g/100 mL
Volume of water at 100C required to dissolve 154.0 g of W: x
723.0 mL of water will dissolve 154.0 grams of solid W.
The solubility of solid W in water at 0°C = 1.72 g/100 mL
Mass of W soluble in 723.00 mL of water at 0°C = m
a) Mass of solid W crystallized out 0°C : 154.0 g- 12.436 g=141.564 g
b) Percent recovery of solid at 0°C:
91.92% is the percent recovery.
