Concentration of ethanol in water solution by distillation from a fermentation is produced a mixture of ethanol in water. the concentration of ethanol is 4 mol %. the ethanol is to be concentrated by distillation, and the distillate must contain 38 volume % ethanol. at 20 °c this is equivalent to 31.5 mass % ethanol. a) convert 31.5 mass % ethanol to mol %. b) a distillation column is at hand. it can provide a distillate of 30 mol % ethanol and a bottom product of 1.0 mol % c) is the process feasible? d) draw a block diagram for the distillation process. e) calculate the yield of ethanol after the distillation, i. e. ethanol in the distillate compared to ethanol in the feed.

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
