7. Draw the placement of each object in the cylinder below based on the density of the objects: a) Silver ring 10.5g/cm3 b) Gold bar 19.3g/cm3 c) Plastic 0.690g/cm3 8. What is the density (g/mL) of an object that has a mass of 42.1grams and, when placed into a. graduated cylinder, causes the water level to rise from 33.2mL to 59.1mL ? 9. A marble ball is placed on a scale and is found to has a mass of 32.2g. If the radius of the marble ball is 1.2cm, what is the density of the marble ball? Volume of sphere =(4/3)r3. 10. A flask and stopper have a mass of 91.5511 grams. A 25.0mL sample of liquid is pipetted into the flask and the flask, stopper, and liquid has a mass of 121.6743 grams. What is the density (g/mL) of the liquid
