Density Quiz Name_______________________ Period__________ *Show all work Formula, numbers with units, answer with the correct unit. Round all answers one place after the decimal, the tenth’s position. Example: 24.5656565656 = 24.6 1. What is the formula for Density? D= 2. For the masses and volumes indicated, calculate the density in grams per cubic centimeters. a. Mass = 489g Volume = 600cm 3 D= b. Mass = 4.0 g Volume = 8 cm 3 D= 3. A block of wood has a mass of 429g. It is 14cm long, 5cm wide and 9cm high. What is its volume and density? V= D= 4. Use the water displacement method to determine the density of an irregular shaped object. The initial water level in the graduated cylinder was 50ml and the final water level after placing the object in water was 64ml. The mass of the solid object was 84g. V= D= 5. Assuming the materials will not mix, show how they would “stack up” in a graduated cylinder. Vegetable oil = 0.91 g/cm 3 Glycerine = 1.26 g/cm 3 Baby oil = 0.82 g/cm Honey = 1.36 g/cm 3 Dawn dish liquid = 1.03 g/cm 3 3 6. Complete the table.
