To determine the organic material in a dried lake bed, the percent carbon by mass is measured at two different locations. To compare the means of the two different locations, it must first be determined whether the standard deviations of the two locations are different. Location 1 Standard deviation = 0.050 Location 2 standard deviation = 0.34 a) What is the calculated ? value for comparing the standard deviations? Fcalc = __________________

Q Search for 20 minutes. Then return, put it down, and weigh yourself immediately three times. Since reporting your weight is a little too personal, I want you to tell me the variation between each reading (called a first derivative measurement). You should see the first weight is somewhat higher than the rest; often as much as 2-3 pounds. What do you th this tells you about your scale's quality? All other data is provided in the lab procedure Questions So, go ahead and answer them, then. a For measuring the block, (part 1) measure something and tell me what it is. Today, definitions. Here are your lab questions: 1. Define significant figure 2. Define accuracy 3. Define precision 4. How many significant figures are present in the measurement 0.053402 mm? How many are in 0.053400? Calculate the following: For three replicate (repeated) measurements, your values are as follows: 3.510 g; 3.565 g; 3.593 Answer the following questions: a. What is the average? b. the percentage error (the…

PROCEDURE 1. On a clean, dry, and flat surface, place a parchment paper, or any non-porous flat sheet. 2. Obtain your medicine tablet. Take note of its mass. [Note: Since this is home experiment and that you might not have a weighing scale at home, assume that given mass of the tablet is pure, with any excipient/(s). For example, a 500 mg ascorbic acid will have a mass of 500 mg as indicated.] 3. Pulverize the tablet into fine powder and trransfer it in a clean and dry vessel or bottle. 5. Add the necessary amount of distilled water to make the desired concentration of stock solution assigned to your group. [Note: Assume that the volume of the solute is negligible compared to the volume of the solution.] Concentration of STOCK SOLUTION, M Concentration of DILUTED SOLUTION, M 0.8 M 0.16 M 6.
