Measuring and Using Density of Precious Metals & Their Alloys as a Tool for Quality Control Density is a measure of substance mass per volume. The symbol mostly used to display density is ρ (rho). ρ = m/V A simple method to determine the density is by using the principle of immersing a body into a fluid on a scale. The fluid level “goes up” according to the body volume and the weight “goes up” according the body’s volume multiplied by the fluid density. When using distilled water (ρ = 1), the extra weight in gram will be equal to the volume in cm³ of the body. An example: Measuring the density of pure silver using this method;
