1. For example, a sample known to contain 60.05% chlorine as chloride was assayed for chlorine, and the following values were obtained: 57.63, 57.68, 57.66 and 57.63. It is obvious from the close agreement between the individual values and the mean value that the indeterminate error of the analysis is very small, or the precision of the measurement is high. Comparing the mean value obtained in the analysis with the true value (60.05) and observing the absolute error calculated.

I have struggled to get the answer. A classmate said it was 159, though I would like to see the steps in demensional analysis, with correct sig figs. thank you! Provide only typed solution answer no handwritten solution needed
Hi:) First of all, Thank you for reading my question. I'm Korean, so there would be some errors.. Sorry for that. I'm doing some stuff for my university, and asking for help because there's a problem I cannot rid of. [Principles of Instrumental analysis 7th edition Chapter 1 question 11] About 'a linear calibration plot', The solution says it 'can be done manually'. I want to know how the graph came out, without using Excel. Guess it'll be similar with question 10, but I have no idea what x, y should be. To get m, I should know about Sxx, Sxy, and to get those, I should calculate sigma xy. And to get xy, I should know what x, y are, but I'm not sure what x, y should be. Does x should be volume (0, 0.5, 1.0. 1.5, 2.0) or [Phenobarbital] (0, 1.0, 2.0, 3.0, 4.0)? I've calcuated both of them, but neither of them was the answer. (I let y as fluorescence of each of solutions; 3.26, 4.80, 6.41, 8.02, 9.56) Would you help me please... Thank you
resubmitting for the 3rd time because the answers are from the automatic solver in a website. again I need a step by step explaination, dont use a website please. I nees someone knowledgeable enough to answer this, if you dont know what is this then please skip, dont waste my tutor questions
I was wondering how to take the anti-log or anti-natural log of a number. I was also wondering if it was possible to do this on a ti-84 plus calculator and the keystrokes to accomplish it if it is possible. Inlcuded is a table of values that requires the anti-logs and anti-natural logs of numbers to work as an example problem.
Find [Hg22*] at 34.50 and 36.5 mL. Compute as well the pHg for all the points.
Please help me I am looking forward of a list (3 sources of error and explain it)
help me. I don't want to see a sentence. Please help me to show my work with convert factor. Don't give me a sentence that makes me confused where to put the right convert factor. Show me the covert factor, please
Show ALL calculations pls. Don't reject if you dont know how to answer I need this. a. What are the average values for vph and vmo? Include calculation of net volume and errorsb. What is/are the component/s of the soda ash sample? c. Calculate the percent composition of the component/s. No need to include error propagation, but you still need to apply Significant Figure rules.
Pls help asap and show all your steps make sure your and is to 2 decimal places pls and thank you!!
Please answer super fast and answer all questions and show calculations For the image attached For 1. a Mass of metal: Trial 1 is 35.0228 g Trial 2 is 35.0915 g Trial 3 is 34.0821 g Mass of water: Trial 1 is 20.0177 g Trial 2 is 20.0250 g Trial 3 is 20.0168 g For delta t of water: Trial 1 is 15.5 C Trial 2 is 15.7 C Trial 3 is 15.1 C For delta t of metal Trial 1 is 80.1 C Trial 2 is 80.2 C Trial 3 is 79.5 C For B my calculated Specific heat is: Trial 1 is 0.462 Trial 2 is 0.467 Trial 3 is 0.466
