Substance A has a density of 3.0g/cm^3 and substance B has a density of 4.0g/cm^3.In order to obtain equal masses of these two substances, the...

Given:

Density of A = 3.0 g/cm^3

Density of B = 4.0 g/cm^3

Ratio of densities of A and B = 3/4 or 3:4

As density is inversely proportional to volumes for equal mass, ratio of volumes of A and B is given by ratio of inverse of densities.

Thus ratio of densities of A and B = (1/3)/(1/4) or 4:3

Answer:

Option B0 of the given choices is correct.
