Aliquid feed stream containing 40 mole perercent benzene, 35 mole percent toluene and 25 mole percent o-xylene is flashed to 120°c and 760 mm hg (14.7psia). hw#2 determine the flow rates and compositions of the vapor and liquid streams after the flash for 100 kg-mole/hr of feed. the vle relationships can be assumed to be ideal. i. e the system obeys raoult's law. c 5004 n nentane and 30% n-

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
