Description

The kettle of a batch still, operating at 1 atm, is charged with a 50 % mol solution of acetone in methanol. We would like to compute the fraction of the initial charge that must be distilled to reduce the composition of the solution remaining in the kettle to 20 % mol of acetone. Two methods are proposed, one using FindRoot and the other using NDSolve.
