Question

Show all your work! Use proper units and significant figures! 1. A piece of metal weighs 44.867 g. When the metal is lowered into 25.0 ml of water in graduated cylinder, the level rises to 28.5 mL. Calculate the density of metal. 2. A solid cube, 2.2 cm on an edge weighed 6.488 grams. Calculate the density of this cube. Will it sink or float in water? Explain. 3. Alcohol has a density of 0.79 g/mL. What is the volume of 22.036 g alcohol? 4. A tin foil has a mass of 0.822 g and measures 10.5 cm by 4.50 cm. Calculate the thickness of this tin foil. given that the density of tin is 7.28 g/em

Explanation / Answer

metal weight= 44.867 g

initial volume V1 = 25 ml

final volume V2 = 28.5 ml

change in volume is volume of metal = V2 - V1 = 28.5 - 25 = 3.5 ml

Since, Density = mass/ volume = 44.867/3.5 = 12.8191 = 12.82 g/ml
