To calculate the specific gravity of a substance, follow these easy steps:
Isolate a known volume of the substance: V.
Use a scale to measure the mass of that volume: m.
Calculate the density of the substance with the ratio: ρ = m/V.
Choose your reference substance and calculate its density: ρr = mr/Vr
Calculate the ratio between the densities: sg =ρ/ρr.
The answer is the specific gravity of the substance. Read more
