Q. IV: Aqueous solutions of the amino-acid L-isoleucine (Ile) are prepared by putting 100.0 grams of pure water into each of six flasks and adding different precisely weighed quantities of lle to each flask. The densities of the solutions at 50.0±0.05°C are then measured with a precision densitometer, with the following results. r (g lle/100 g H2O) 0.000 p (g solution/cm³) 0.8821 0.98803 0.98984 1.7683 0.99148 2.6412 3.4093 0.99297 0.99439 4.2064 0.99580 (a) Plot a calibration curve showing the mass ratio, r, as a function of solution density, p, and fit a straight line to the data to obtain an equation of the form r = ap + b. (b) The volumetric flow rate of an aqueous lle solution at a temperature of 50°C is 150 L/h. The density of the sample of the stream is measured and found to be 0.9940 g/cm³. Use the calibration equation to estimate the mass flow rate of lle in the stream (in kg lle/h). (c) It has been later discovered that the thermocouple used to measure the stream temperature…
