Justine just added a new rock to her collection. To learn what type of rock it is, Justine wants to calculate the rock's density. She first weighs the rock and finds that its mass is 48 g. To find its volume, she puts it in a container filled with 80 mL of water. When the rock is added, the water level changes to 100 mL, which is equal to 100 cm3. The diagram below shows the water level change.
