The oxygen mass transfer coefficient in fermentation vessels is determihed TPom measurements using the formula: OTR kLa CAL-CAL where kLa is the mass transfer coefficient, OTR is the oxygen transfer rate, is the solubility of oxygen in the fermentation broth, and CAL is the dissolved oxygen concentration. CA is estimated to be 0.25 mol-m-3 with an uncertainty of +4%; CAL is measured as 0.183 mol-m-3 also with an uncertainty of +4%. If the OTR is 0.011 mol-m-3.s-1 with an uncertainty of ±5%, what is the maximum possible error associated with kLa expressed as relative error (%)?

A 25mL volumetric pipet is used to deliver a sample of the stock solution marked “0.6000M X2SO4” into a 100mL volumetric flask. Distilled water is added to the flask until it is about 3/4thfull, the solution is mixed well, then more water is added to fill it up to the calibration mark, then it is mixed again. Calculate the concentration of X+ion in the dilute solution made above.
