Please help, I don't understand chemistry at all. Density is a physical property of a molecule that’s measured as mass per unit volume.
(a) Given that density is usually expressed in the units of g/cm3
, calculate the density of a cube of plastic that
has a mass of 2.331 g and an edge length of 1.500 cm (volume of a cube is V = l^3
).

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
