Student constructs and completes chart.

complete the following questions, copy
1. You have just calculated the density of each of the 5 crowns. Refer to the chart "Density of Common Substances" and explain why the property of density is valuable in the identification of a substance.
2. Using the evidence from your density calculations, and the chart "Density of Common Substances", identify the crown made of pure gold.

Here's what you need to do:
1. Review the concept of density at density.
2. Copy and complete the chart that organizes the following data about the 5 crowns: all of the crowns look identical and have a volume of 180 cm3. The 5 crowns have the following different masses: 1890 g, 486 g, 1404 g, 3474 g, and 2034 g.
