2. Suppose you are given a metal object that you weigh on a centigram balance. The recorded mass is 16.78 g. The volume of the object was determined by carefully sliding the metal object into a graduated cylinder containing 27.8 mL of water. The water in the cylinder was displaced up to a final volume of 37.7 mL. 37.7ml-27.8mL = 9.9 a. Determine the density of the metal object m D= 16.789 V 1.7 9.9ml b. Which measurement, mass or volume, limits the number of significant figures? Why?

Pre-Lab Questions
Each lab will include a small set of questions to be answered prior to attending lab. Answer these
questions directly on these worksheets. Show all of your work. Attach additional paper if necessary.
Round the final answer to the proper sig figs and include units. Circle your final answer.
1- Accurate Measurement and Density
1. In your own words, explain the difference between accuracy and precision.
Accuracy
is now close valves are to the frue value
VS Precision is how close thoce accuracy values are to eacho-
2. Suppose you are given a metal object that you weigh on a centigram balance. The recorded mass is
16.78 g. The volume of the object was determined by carefully sliding the metal object into a
graduated cylinder containing 27.8 mL of water. The water in the cylinder was displaced up to a
final volume of 37.7 mL.

b. Which measurement, mass or volume, limits the number of significant figures? Why?
Volume because it has the least amount of
figures which is 2.
3. Now suppose that you carefully repeat your experiment using an analytical balance and a
graduated cylinder that can be read to the nearest 0.01 mL. The recorded mass is 16.7755g. The
graduated cylinder readings before and after introducing the metal object are 27.86 mL and 37.86
mL respectively.
