Certified Reference Material (CRM), GSS-5, is certified to contain 40.67 ± 3.33 mg/kg of Ni in soil. An analysis of the CRM gives values of 40.39, 41.98, 43.64, 44.38, and 45.96 mg/kg. Determine the tcalc. value and determine if your results differ from the expected results at the 90 % confidence level?

Before investigating the scene, the technician must dilute the luminol solution to a concentration of 2.00x10-2 M. The diluted solution is then placed in a spray bottle for application on the desired surfaces. How many moles of luminol are present in 2.00 L of the diluted spray? Express your answer with the appropriate units.

Also follow the unit specified in each question. Do NOT put its unit in your answer because its unit is shown already in the questions.
A student determines the concentration of an unknown sample using two different methods. Each method has three different trials; the average, standard deviation, and percent error produced by each method is listed below. Method 1 Average: 10.56 M NaOH Standard deviation: 1.35 M NaOH Percent error: 1.25% Method 2 Average: 10.92 M NaOH Standard deviation: 1.02 M NaOH Percent error: 3.45% Which method was more accurate? How can you tell?

Explain the use of plans and their importance in assessing the quality of pharmaceutical products. Provide a step-by-step design of a sampling plan based on a normal inspection for a 75,000 tablets with an AQL of 0.12% using the attached table (at the end of exam paper).
The standard solution is prepared by dissolving a known mass of zinc pellets with conc. HCl. The solution is then neutralized, transferred into a 250 mL volumetric flask and filled to the calibration mark. If 0.9809 g of Zn was weighed using an electronic balance with a relative uncertainty of ± 0.01 % and the 250 mL volumetric flask has a known relative uncertainty of ± 0.06 %, what would be the absolute uncertainty of the concentration of the solution? The molecular weight of the zinc pellets is 65.39 g/mol
You are preparing a 100.0 mL standard solution needed for titration analysis. The NaOH (40 g/mol) pellets are measured to be 0.5341 g in a balance with acceptable uncertainty of +0.001 g. Mass of the pellets is recorded after taring the container. The pellets are put in a beaker and added with 50 ml distilled water measured by a graduated cylinder. The solution is then quantitatively transferred to a 100-mL volumetric flask with uncertainty of ±0.08 mL and diluted to a 100-mL mark. What is the concentration (M) of the solution and estimate its uncertainty by propagation? Assumption: There is no uncertainty in molar mass. Express your answer as C+/- u M.
