Basic Analytical Chemistry - Evaluation of experimental data
Look at the following solution to this sig fig problem and tell me what I have done wrong. Then show me the correct and best way to solve this problem.
Note: Use de rule addition/subtraction.
ADDITION/SUBTRACTION: You must show the least degree of precision even if your calculator does not
245.956 g – 245.756 g = 0.2 g according to your calculator. But your degree of precision is the 0.001 g and so your correct answer is 0.200 g
23.789 g + 81.211 g = 105 g according to your calculator. But your degree of precision is the 0.001 g and so your correct answer is 105.000 g
The degree of precision is not necessarily about the number of places behind the decimal point. In these examples consider ambiguous zeros to be non significant
4500 m + 21 m = 4521 m according to your calculator. But your degree of precision is the 100’s place and so your correct answer is 4500 m
90 cm + 45.21 cm = 135.21 cm according to your calculator. But your degree of precision is…

- Which method should lead to greater precision? Which method actually is more precise? Explainarrow_forwardWhile creating a piece of art work, a student becomes curious about the ink he is using to create his art. He wonders if the in is a pure substance or a mixture. The ink appears to be uniform throughout, but separates when a chromatography experimer is performed on it, leaving multiple marks of different colors along the chromatography paper. Using his observations of the properties of the ink, the student can classify it as a heterogeneous mixture. solution. compound. element.arrow_forwardSuppose you were measuring out an organic liquid, and some of it is evaporated after you have performed the volumetric measurement while you are weighing out the sample. What effect would this have on the densities you calculated? Will you overestimate or underestimate the density of the liquid? Would this cause poor accuracy, low precision, or both? Explain briefly.arrow_forward
- Hexane (C6H14, density = 0.766 g/cm3), perfluoro-hexane (C6F14, density = 1.669 g/cm3), and water are immiscible liquids; that is, they do not dissolve in one another. You place 10 mL of each in a graduated cylinder, along with pieces of high-density polyethylene (HDPE, density = 0.97 g/cm3), polyvinyl chloride(PVC, density = 1.36 g/cm3), and Teflon (density = 2.3 g/cm3). None of these common plastics dissolves in these liquids. Describe what you expect to see.arrow_forwardYou can analyze for a copper compound in water using an instrument called a spectrophotometer. [A spectrophotometer is a scientific instrument that measures the amount of light (of a given wavelength) that is absorbed by the solution] The amount of light absorbed at a given wavelength of light (A) depends directly on the mass of compound per liter of solution. To calibrate the spectrophotometer, you collect the following data: Plot the absorbance (A) against the mass of copper compound per liter (g/L), and find the slope (m) and intercept (b) (assuming that A is y and the amount in solution is x in the equation for a straight line, y = mx + b). What is the mass of copper compound in the solution in g/L and mg/mL when the absorbance is 0.635?arrow_forwardI need help rounding this value by looking at the limiting precision in my calculation.arrow_forward
- The Calcium content of a banana sample was homogenized and measured. Are the results comparable? Do they have the same precision? Please use data given.arrow_forwardWhat is the difference between precision and accuracy in analytical chemistry? Give an example from everyday lifearrow_forwardA researcher would like to determine whether there is any relationship between students’ grades and where they choose to sit in the classroom. Specifically, the researcher suspects that the better students choose to sit in the front of the room. To test this hypothesis, the researcher asks her colleagues to help identify a sample of n = 100 students who all sit in the front row in at least one class. At the end of the semester, the grades are obtained for these students and the average grade point average is M = 3.25. For the same semester, the average grade point average for the entire college is μ = 2.95 with σ = 1.10. Use a two-tailed test with α = .01 to determine whether students who sit in the front of the classroom have significantly different grade point averages than other students.NOTICE that you are asked to use α = .01!
