A tank is filled to 80% of its capacity with a saturated solution of MgSO4. The solution contains 1800 kg of MgSO, and is kept at 360 K. The tank is opened and the solution cools to 285 K forming MgSO4.8H2O crystals. Calculate the resultant yield of crystals and the capacity (volume) of the tank. Use the information below: • Density of the solution is 1900 kg/m • Solubility of M£SO4 per 100 parts of water by mass is 50 at 360 K and 33 at 285 K. • Assume there is negligible evaporation • Molecular weight of MgSO, is 120 kg/kmol • Molecular weight of H3O is 18 kg/kmol |C1 – C2(1 – E)| li- c2 (R – 1) Y = RW,

Transcribed Image Text:A tank is filled to 80% of its capacity with a saturated solution of MgSO4. The solution contains 1800 kg
of MgSO, and is kept at 360 K. The tank is opened and the solution cools to 285 K forming MgSO4.8H2O
crystals. Calculate the resultant yield of crystals and the capacity (volume) of the tank.
Use the information below:
• Density of the solution is 1900 kg/m
• Solubility of M£SO4 per 100 parts of water by mass is 50 at 360 K and 33 at 285 K.
• Assume there is negligible evaporation
• Molecular weight of MgSO, is 120 kg/kmol
• Molecular weight of H3O is 18 kg/kmol
|C1 – C2(1 – E)|

Y = RW,
Expert Solution
Step 1
Given data:
Amount of MgSO4 in the feed = 1800 kg
Temperature of feed = 360 k
Temperature of mother liquor = 285 K
Density of the solution = 1900 kg/m3
Solubility of MgSO4 at 360 K = 50/100 parts water
Solubility of MgSO4 at 285 K = 33 /100 parts water
Molar mass of MgSO4 = 120 kg/kmol
Molar mass of H2O = 18 kg/kmol
Step by step
