Distillation using mccabe-thiele method. a rectification column is fed 100 kg mol/h of a mixture of 50 mol % benzene and 50 mol % toluene at 101.32 kpa abs pressure. the feed is liquid at the boiling point. the distillate is to contain 90 mol % benzene and the bottoms 10 mol % benzene. the reflux ratio is 4.52: 1. calculate the kg mol/h distillate, kg mol/h bottoms, and the number of theoretical trays needed using the mccabe-thiele method.

In a laboratory determination of the atomic weight of tin, a sample of tin is weighed in a crucible. nitric acid is added, and the reaction proceeds to give a hydrated tin(iv)oxide plus no2and h2o. the hydrated tin(iv)oxide is then heated strongly and reacts as follows: sno2.xh2o(s)sno2(s)+ xh2o(g)the sno2is finally cooled and weighed in the crucible. explain the effect on the calculated atomic weight of tin that would result from each of the following experimental errors: (a)considerable spattering occurs when the nitric acid is added to the tin.(b)the hydrated tin(iv)oxide is not heated sufficiently to change it completely to tin oxide.
