Hi there, I'm having trouble with this problem. What would be the correct answer and the reasoning?

In the technique of high performance liquid chromatography (HPLC) the peak area response for a particular analyte is directly proportional to concentration Analgesic tablets typically consist of aspirin and caffeine as the active ingredients, the remainder made up of inert binding material. The concentrations of aspirin and caffeine may be routinely monitored using HPLC, whereby the peak areas obtained from a solution of the tablet are compared with those obtained from standard solutions of the analytes. In an analysis to determine the concentration of caffeine in such a tablet, the following data were recorded: Solutions Analysed: Tablet Sample: Mass of tablet (dissolved in 250 cm methano): 0.523 g Caffeine Standard: Mass of caffeine (diessolved in 500 cm methanol) 0.105 g HPLC results: Solution Peak Area (catfeine) 1. Tablet Sample 325 2. Caffeine Std. 865 The concentration of caffeine in the tablet (expressed as a mass (w/wl percentage) was Oa 1.89 Ob 13.4 O 3.77 Od. 267 Oe 7.54 You…

on the last part of the problem where it is x=( 10-10 x 0.25)1/2=5x10-6 M When I plug that into my calculator I get 1.25 an not 5x10-6 what am I doing wrong

O GASES Using Charles's Law Jacqueline An arctic weather balloon is filled with 48.4 L of helium gas inside a prep shed. The temperature inside the shed is 9. °C. The balloon is then taken outside, where the temperature is -42. °C. Calculate the new volume of the balloon. You may assume the pressure on the balloon stays constant at exactly 1 atm. Round your answer to 3 significant digits.

In a survey of 1000 large corporations, 250 said that, given a choice between a job candidate who smokes and an equally qualified nonsmoker, the nonsmoker would get the job (USA Today).(a) Let p represent the proportion of all corporations preferring a nonsmoking candidate. Find a point estimate for p.(b) Find a 0.95 confidence interval for p.(c) As a news writer, how would you report the survey results regarding the proportion of corporations that hire the equally qualified nonsmoker? What is the margin of error based on a 95% confidence interval?

Density of Zinc: Consider the data and results from the density of zinc determination. Now focus on the average absolute error associated with the calculated average density of zinc. Which measurement contributes the most relative error to this value? Given that measurement and its associated absolute error, is the calculated average absolute error reasonable and why? What aspect of the experiment limited the measurements the most?
