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

Listenbase your answer to the question on the information below.nuclear radiation is harmful to living cells, particularly to fast-growing cells, such as cancer cells and blood cells. an external beam of the radiation emitted from a radioisotope can be directed on a small area of a person to destroy cancer cells within the body.cobalt-60 is an artificially produced radioisotope that emits gamma rays and beta particles. one hospital keeps a 100.0-gram sample of cobalt-60 in an appropriate, secure storage container for future cancer treatment.which choice represents the correct product for the beta decay of the co-60? fe-60ni-60fe-61ni-61
