DON’T FORGET TO SHOW ALL WORK: Equation. Plug in #’s. Answer (round to nearest tenth) Units

1. Frank has a paper clip. It has a mass of 9.2 g and a volume of 14.3cm 3. What is its density? D = m = 9.2 g = v 14.3cm 3 D = 0.6 g/cm 3

2. Frank also has an eraser. It has a mass of 3.3 g, and a volume of 1.5cm 3. What is its density? D = m = 3.3 g = 2.2 v 1.5cm 3 D = 2.2 g/cm 3

3. Jack has a rock. The rock has a mass of 6g and a volume of 3cm 3. What is the density of the rock? D = m = 6 g = 2 v 3cm 3 D = 2.0 g/cm 3

4. Jill has a gel pen. The gel pen has a mass of 8g and a volume of 2cm 3. What is the density of the rock? D = m = 8 g = 4 v 2cm 3 D = 4.0 g/cm 3

5. Osmium is a very dense metal. What is its density if 50 g of the metal occupies a volume of 2.22cm 3 ? Show all work. D = mass = 50 g = volume 2.22 cm 3 D = 22.5 g/cm 3
