(6.2C) Find the mass of the rock. (354.6g) 3. (6.3A) The diagram below shows 20 grams of 2 different materials. Compared to material A, material B has a different … (volume) 4. (6.4A) The picture below shows a small, shelled animal. Which tool should be used to measure the mass of this shelled animal?(triple beam balance – g) 5. (6.4A) Tools needed to test the density of unknown liquids most likely include – (graduated cylinder and triple beam balance) 6. (6.6B) When 7. (6.6B) Twenty you add a rock to 40ml of water in a graduated cylinder, the water rises to 90ml. The mass of the rock is 20 g. What is the rock’s density? (.4g/ml) milliliters of a liquid has a mass of 25 grams. What is the density of this substance? (1.25g/ml) 8. (6.6B) Determine (.5g/ml) the density for a material that has a mass of 5 grams and a volume of 10mL.
