Detailed explanation-1: -The mass per unit volume of a substance is called density (density = mass/volume).
Detailed explanation-2: -The formula for density is: D=m/v. The unit for mass is kilograms (kg)/grams (g) and volume in centimetres cubed (cm3) or metres cubed (m3).
Detailed explanation-3: -The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume). The mass of atoms, their size, and how they are arranged determine the density of a substance. Density equals the mass of the substance divided by its volume; D = m/v.
Detailed explanation-4: -Volume is a measure of the amount of space that a substance or an object takes up. The basic SI unit for volume is the cubic meter (m3), but smaller volumes may be measured in cm3, and liquids may be measured in liters (L) or milliliters (mL).
Detailed explanation-5: -The mass of a unit volume of a substance is called its density.
