How do you calculate mass using density and volume?

As a result, the question asks us to determine the mass of the supplied sample if we are given the substance's density and volume.
We are familiar with concepts like mass, volume, and density from our lower classes.
The three combinations are often utilised in physics, but they are also employed in chemistry when dealing with pure substances, such as pure solids and liquids.

Density is the mass of substance per unit volume.

$\mathrm{Density}=\frac{\mathrm{Mass}}{\mathrm{Volume}}$

Therefore; mass can be calculated using density and volume as;

$\mathrm{Mass}= \mathrm{Density}\times \mathrm{Volume}$

We typically compare and compute the densities of pure compounds because, if the densities of the pure compounds in the mixture are known, we may forecast the many atom combinations that might be conceivable and estimate the various compositions of various sorts of mixtures.
The word "mass" is used to describe the quantity of a solute in a solution as well as the mass of the atoms contained inside a crystal's lattice. When discussing solutions in liquid states, we typically associated the words volume and mass to density when discussing solid states.

Hence, option B is correct.
