11 bought a necklace which the seller said was made from silver. I decided to check if the necklace was truly silver. The density should be about the density of silver. The density the experiment in the lab. was done using water and a graduated cylinder to collect the following data: Mass of necklace = 12.306 g Volume of just water in the graduated cylinder = 7.64 cm3 Volume of water + necklace in the graduated cylinder = 8.81 cm3 1. What is the measured VOLUME of the necklace 2. What is the density of the necklace? Show all working 3. Considering just the data in the table and the calculations in the previous two questions: If a more precise balance had been used (i.e. the mass was measured with an additional significant figure), would the number of significant figures in the calculated density increase, decrease or remain the same? Explain in no more than one sentence. 4. Is the necklace made of silver? Density of silver is 10.49g/ cm3. Tick a. or b.: a. YES b. NO 5. Why is it that a larger piece of a metal that has a higher mass, has the same density as a smaller piece of metal that has a smaller mass? 6. Consider the procedure used to measure the volume of irregularly shaped solids. Why is it important to measure the mass before measuring the volume?

Question
Transcribed Image Text:1I bought a necklace which the seller said was made from silver. I decided to check if the
necklace was truly silver. The density should be about the density of silver. The density the
experiment in the lab. was done using water and a graduated cylinder to collect the
following data:
Mass of necklace = 12.306 g
Volume of just water in the graduated cylinder = 7.64 cm3
Volume of water + necklace in the graduated cylinder = 8.81 cm3
1. What is the measured VOLUME of the necklace
2. What is the density of the necklace? Show all working
3. Considering just the data in the table and the calculations in the previous two
questions: If a more precise balance had been used (i.e. the mass was measured with
an additional significant figure), would the number of significant figures in the
calculated density increase, decrease or remain the same? Explain in no more than one
sentence.
4. Is the necklace made of silver? Density of silver is 10.49g/ cm3. Tick a. or b.:
a. YES
b. NO
5. Why is it that a larger piece of a metal that has a higher mass, has the same density as a
smaller piece of metal that has a smaller mass?
6. Consider the procedure used to measure the volume of irregularly shaped solids. Why is it
important to measure the mass before measuring the volume?
