mass spectral measurements were made on 10 replicate low concentration Ni-EDTA samples: 146.9 , 111.5 , 125.7 , 140.7 , 109.7 , 179.1 , 130.7 , 135.3 , 124.7 , and 142.3 counts. Ten measurements of a blank had a mean measurement of 38.3 counts. A sample containing 2.00 μM Ni-EDTA gave a measurement of 1597 counts. Estimate the signal and detection limit for Ni-EDTA.

Two sets of measurements of ethanol concentration in a sample of vodka were made using the same instrument, but on two different days. On the first day, a standard deviation of s1 = 9 ppm was found, and on the next day s2 = 2 ppm. Both datasets comprised 6 measurements. Can the two datasets be combined, or is there is a significant difference at 95% confidence between the datasets, and should we discard one of them? Hint: Begin by...

An EDTA standard was made at 22.5 °C by dissolving 0.6206 g (uncorrected mass) of Na2H2EDTA·2H2O in a 499.859 mL volumetric flask. Several 9.9873 mL aliquots of unknown were titrated for total divalent metal ions, and required an average of 23.197 mL of EDTA solution to reach the end point. After precipitation of Mg2+ from several additional 9.9873 mL aliquots of unknown, an average of 15.660 mL of titrant was required to reach the end point. All blanks were zero....

Two water samples were analyzed for their copper content by atomic absorption spectroscopy. After 5 replicate analyses, the first water sample was found to have 12.6± 0.9 mg/L copper. After 6 replicate analyses, the second water sample was found to have 13.1± 0.6 mg/L copper. Is the copper content in these water samples significantly different? Report your answer in a full sentence, including all necessary information to explain how confident you are about your answer. Answer: Since the calculated t...

As a result of an experiment following measurements were obtained from a cell: intracellular Na+ concentration of 10 mM, intracellular K+ concentration of 140 mM, intracellular Cl- concentration of 5 mM, intracellular Ca2+ concentration of 0.0001 mM, extracellular Na+ concentration of 150 mM, extracellular K+ concentration of 5 mM, extracellular Cl- concentration of 120 mM, extracellular Ca2+ concentration of 5 mM. Using these values calculate equilibrium potential for Ca2+ ion in these cells. (RT/F = 26.7 mV, 37oC)
