Density

Problem 1 Given: mass = 0.196 g volume= 100 ml Find: density Solution: DV M

Problem 2 Given: length of each side = 3.0 cm volume = 3.0 cm x 3.0 cm x 3.0 cm = 27 cm 3 mass = 27 g Find: density Solution: 3 cm DV M

Problem 3 Given: volume water = 2.0 ml volume water + object = 7.0 ml volume water change = 7.0 ml – 2.0 ml = 5.0 ml 1mL = 1cm 3 volume of object = 5.0 cm 3 mass = 25 g Find: density Solution: 2.0 ml 7.0 ml D V M

Problem 4 Given: volume copper = 10.0 cm 3 mass copper = 89.6 g Find: density Solution: DV M

Problem 5 Given: density silver = 10.5 g/cm 3 density gold = 19.3 g/cm 3 volume silver = 5 cm 3 volume gold = 5 cm 3 Find: mass of gold and silver Solution: DV M
