Part A: A sample of gold has a mass of 38.6 grams and a volume of 2 cm3. What is the density of gold? Part B: A sample of iron has a mass of 46.8 grams and a volume of 6 cm3. What is the density of iron?
Part C: Of the two samples described in parts A and B, the sample of iron has more mass and feels heavier than the sample of gold. Does this mean that the density of iron is greater? Explain.
Part D: Water has a density of 1.0 g/cm3. What is the mass of 10.0 cm3 of water?
Part E: Some substances have the same chemical composition, but their atoms are arranged differently. A classic example is carbon. A pencil lead is made of graphite, which contains only carbon atoms. A diamond also contains only carbon atoms. However, the carbon atoms in a diamond are packed more closely together. Would you expect the density of graphite and a diamond to be the same? Explain your answer.
