Answer:
Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume.
Explanation:
if you don't understand Density is a measure of how compact the mass in a substance or object is. … Density is a measure of mass per unit of volume. In general, gases have the lowest densities, but these densities are highly dependent on the pressure and temperature which must always be specified. If you don't understand after that then …..
