Whoever gets this correct I will mark brainiest and give u more points.
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
).
(b) Draw two liquids in a graduated cylinder on a separate sheet of paper. You won’t submit the drawing as part
of your answer. Liquid A has a density of 1.004 g/cm3 and Liquid B has a density of 0.6223 g/cm3
. Assume they
don’t mix. Label which liquid is on top and which liquid is on bottom, and then draw the cube where you would
expect it to be if it’s dropped into the graduated cylinder with these two liquids.
Explain the location for liquid A, liquid B, and the cube in the graduated cylinder.
