Andrew needs to find the density of a small, irregularly shaped pebble he found near the river. He put the pebble on a scale to determine the mass is 16,2 grams. After finding the mass, he uses a graduated cylinder to find the volume. He puts 50.0 mL of water into the graduated cylinder, then puts the rock inside it. After putting rock into the graduated cylinder, it now reads 62.0 ml. What is the
density of the pebble?
O 0.14 g/ml
O 0.32 g/mL
0.26 g/mL
135 g/mL
