Chapter 1, Problem 38E
The beakers shown below have different precisions.
- a. Label the amount of water in each of the three beakers to the correct number of significant figures.
- b. Is it possible for each of the three beakers to contain the exact same amount of water? If no, why not? If yes, did you report the volumes as the same in part a? Explain.
- c. Suppose you pour the water from these three beakers into one container. What should be the volume in the container reported to the correct number of significant figures?

A pycnometer (Figure 1) is a special flask often used for measuring the densities of substances. Given the data below, calculate the density (in g/mL) of liquid 1.
Mass of empty pycnometer 51.870 g
Mass of pycnometer when filled with liquid 1 86.313 g
Volume of pycnometer 39.24 mL
13. The mass of water delivered by a buret is 11.8159 g at 15 °C. What is the calculated actual volume
based on significant figures? NOTE: You will report the actual volume deliver in Expt 1 to two decimal
places since all class A 50 mL buret readings are to two decimal places.
