Part a through c please a) The density of aluminum is 2.699 g/mL. If a block of aluminum occupies 25.6 cm3 , its mass in pounds is (Given: 453.6 g = 1 lb), a) 0.152 lb b) 69.1 lb c) 431. lb d) 3.14 x 103 lb b) A student collects the following data on a metal sample by weighing it on a piece of weighing paper. The volume of the sample was determined by water displacement in a graduated cylinder. The collected data was: Mass of paper = 0.452 g Mass of paper + metal = 72.943 g Volume of water = 15.2 mL Volume of water + metal = 19.0 mL What is the density of the metal? a) 2.7 g/mL b) 3.8 g/mL c) 7.8 g/mL d) 19. g/mL c) A piece of gold foil has a mass of 0.023 g and a length of 10.04 cm and a width of 5.11 cm. If the density of gold is 18.91 g/cm3, what is the thickness of the foil? a) 3.3 x 10-4 cm b) 3.1 x 10-3 cm c) 2.4 x 10-5 cm d) 2.4 x 10-3 cm
