Transcribed Image Text:

A saturated solution of MgSO4 at 353 K (80° C) is cooled to 303 K (30°C) in a crystallizer. During cooling, 4% solution is lost by evaporation of water. Calculate the quantity of the original saturated solution to be fed to the crystallizer per 1000 kg crystals of MgSO4.7H2O. Solubilities of of MgSO4 at 303 K and 353 K are 40.8 and 64.2 kg / 100 kg of water respectively. (12) (April '98).
