Density is mass divided by volume.
<span>Because there is a permanent dipole between the Br and Cl atom. The Cl atom has a higher electronegativity, so it will tend to pull the "shared" electrons formed in the bond to its pole, creating a permanent dipole and partial electron deficiency on the bromine atom.</span>
When you talk about importance, it should depict the impact of investigation on a larger scale. It should benefit not only your own interests, but to a number of people. From the choices, letter A seems petty. Letter B does not really give a direct importance. Letter C is significant, but not so compared to D. Choice D is the main objective of investigations: in pursuit of discoveries.
The density formula is:
density=mass/volume.
d=3.5g/2cm^3
d=1.75 g/cm^3
The density of the sample is 1.75 g/cm^3.
