PRELABORATORY EXERCISE:
1. Compare and contrast accuracy and precision.
2. A student performs the experiment and acquires a mass of 9.25g for a 10mL addition of
water. What is their percent error for this trial?
3. A student performs the experiment and acquires a mass of 25.28g for a 10mL addition of
water. What is their percent error for this trial?
Documentation: In addition to your data sheet below
being filled and post lab questions, all labs need to
have a separate file of a single pdf (not individual
uploads of pictures) as supporting evidence of your
measurements. There are a couple of reasons you are being asked
to do this:
1. As a lab science class, you are expected to demonstrate
mastery of equipment use.
Che
2. I need to see that it is you doing to the lab.
3. I also need to provide feedback on your measurements
compared to the actual reading. This is where significant
figures come in.
