In physics and chemistry, density is the estimation of the entities with mass occupied in a space. It is calculated by dividing mass by volume. Thus, option A is correct.
Density is the physical property that has been defined by the mass and the volume of the object or the substance is given. The density of any object is estimated by,
D = M ÷ V,
Here D represents density in grams per cubic centimeter, mass (M) in grams, and volume (V) in cubic centimeters.
The increase in mass increases the density and shows the direct relationship between the both. On the other hand, the increase in volume decreases the density and shows an inverse relationship.
Therefore, option A. the density is calculated as mass divided by volume is correct.
