    4 3. Density measurement principles 3.1. Density density refers to the total mass of a sample per unit volume. M ρ = v ρ : density m : mass v : volume 3.2. Specific gravity specific gravity refers to the ratio of the density of a sample to the density of pure water at 4°c under a pressure of 1013.25...

    5 3.4. Density of a solid the density of a solid can be obtained according to the weight of the sample in air, the weight of the sample in liquid and the density of the liquid. A ρ = x ( ρ 0 - d) + d a - b ρ : density of sample a : weight of sample in air b : weight of sample in liquid ρ 0 : density...

    6 4. Error factors there are several things that can affect the accuracy of a density measurement. 4.1. Buoyancy of air a density measurement is influenced by an upward force of 0.0010 to 0.0014 g/cm 3 (buoyancy of air). The density of air can be obtained by the equation below: 0.0012932 p (hpa) d =...

    7 4.3. Temperature of liquid the density of the liquid that is used for measuring the density of a solid varies with the liquid temperature. Therefore, the decimal places beyond the first decimal place of the measured value contain errors. Obtain the density of a liquid according to the temperature ...
