Suppose a 20 gram cube of aluminum were cut into four equal parts. how would the density of one part be related to the density of the whole cube?

It will remain the same, since the formula for density is D=m/v
since mass is directly proportional with volume (due to its dimensions) if you cut a piece of aluminium in four the mass will get smaller as well as the size, therefor the volume.

Ibelieve y y even though i've only taken chemistry for one year

The question is incomplete. complete question is attached belowanswer: correct answer is option b  i.e.  solid particles  reason: filter paper has small pores, through which smaller particles can pass through. however, solid particles  have relatively larger size. hence, they are least likely to pass through.
