i need the answer to the following problem please inclusiveshould be the steps for getting the answer. the solubility of cholesterol in 95% ethanol is 32.5 mg/mL at370C and 11.5 mg/mL at 70C. how much 95%ethanol is required to dissolve 1 g of cholesterol at370C? if that volume of warm, saturated solution iscooled in a refrigerator to 70C, how much cholesterolwill crystallise? i need the answer to the following problem please inclusiveshould be the steps for getting the answer. the solubility of cholesterol in 95% ethanol is 32.5 mg/mL at370C and 11.5 mg/mL at 70C. how much 95%ethanol is required to dissolve 1 g of cholesterol at370C? if that volume of warm, saturated solution iscooled in a refrigerator to 70C, how much cholesterolwill crystallise?

Explanation / Answer

The solubility of cholesterol in 95% of ethanol = 32.5mg/mL Therefore to dissolve 1.0 g of the ethanol, volume ofthe ethanol required = 1.0 g* 1 mL/32.5*10-3 g                                                                                                               = 30.76 mL is required At 70C, the solubility of the cholesterol inthe 95% ethanol =11.5 mg/mL If we cool the solution from 370C to70C, Then the mass of the ethanol crystalized = 32.5 mg - 11.5 mg                                                             = 21.0 mg of ethanol will crystalize
