(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).
(explain/or do density(calculate it) find volume first. then show work of density divided by volume give proper units.) (Density is a physical property of a molecule that’s measured as mass per unit volume.) (Measurement in chemistry. Think about the density of different substances. PLEASE SHOW WORK)

To find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? a) when more work was done, the couch was moved the same distance. b) when more work was done, the couch was moved less. c) when more work was done, the couch was moved further. d) when more work was done, the couch wasn't moved at all.
