Def of density in chemistry
WebThe density of an object or a substance is its mass, divided by its volume. We use the formula: \(density = mass ÷ volume\) to calculate the density of an object or substance. WebMay 22, 2024 · In words, the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance. The standard SI unit is kilograms per cubic meter ( kg/m3 ). The Standard English unit is pounds mass per cubic foot ( lbm/ft3 ). The density (ρ) of a substance is the reciprocal of its specific volume (ν).
