1. A copper wire is 26.61 cm long and weighs 1.265 g. The density of copper is 8.933 g/cm3.
A. What is the radius of the wire in millimeters?
B. What is the diameter of the wire?
2. An empty beaker weighs 22.47 g. When completely filled with water, the beaker and its contents have a total mass of 437.15 g. What volume does the beaker hold? Use ?=1.00 g/mL as the density of water. How much would the beaker and its contents weigh if it was completely filled with mercury? The density of mercury is ?=13.5 g/mL.
3. A 4.1299 g piece of aluminum wire with a circular cross-section is 28.21 cm long with a density of 2.6989 g/cm3.
