1.If you have an object that has a mass of 8 grams and a volume of 4 cm3 , what is the objects density?
2.A rock is found in nature with a mass of 36 grams. When using the water displacement method, the water level began at 30ml and rose to 36ml once the rock was put in. What is the volume of the rock?
1. Density = 8g/4cm^3 = 2g/cm^3.
