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 accepted value is 3.62 g) C. There is a±5% error in the accuracy; is the label mass true.

5) How will each of the following experimental errors influence the results of your calculated densities you reported? State whether the error will tend to make your density results too large, too small or unchanged. Explain why this would occur by identifying which measurements would be affected (high or low) and how this would affect the calculated density. a) In method 2, the metal cylinder you used had a number of air bubbles on its when immersed in the water.
