MEASUREMENT OF DENSITY Introduction

density  The mass density of an object is defined as its mass per unit volume This parameter can be expressed using several different units, including Density equals the mass of the substance divided by its volume; D = mv Objects with the same volume but different mass have different

The density equation is density equals mass per unit volume or D = M V The key to solving for density is to report the proper mass Density = mass ÷ volume = 500 ÷ = 200 k g m 3 text{Density } = text{ mass } div text{ volume } = 500 div = 200 kgm^{3}

Density is an intensive property, which means the density does not change as the amount of the substance present changes This contrasts with mass (an extensive Modern digital density meters are based on the oscillating U-tube principle The tube, usually a U shaped glass tube, is excited and starts to oscillate at a
