17 Οκτ 2024 · Conversion factors can also be constructed for converting between different kinds of units. For example, density can be used to convert between the mass and the volume of a substance. Consider mercury, which is a liquid at room temperature and has a density of 13.6 g/mL. The density tells us that 13.6 g of mercury have a volume of 1 mL.

Equation 3: Converting the true density of a sample ρ true into apparent density ρ app. This conversion takes the true density of air (ρ air ≈ 0.0012 g/cm³) and true density of brass (ρ brass = 8.4 g/cm³) or steel (ρ steel = 8.0 g/cm³) into account.
Density measurement. Density (d) is calculated from the mass (m) and volume (V) of a substance by the formula: \[d = \frac{m}{V}\nonumber\] Mass is usually measured using an analytical balance. The volume of liquids can be measured using a graduated cylinder, pipet, or density bottle.
Measure the laboratory temperature t, which determines the temperature of examined liquids and solid objects. Table 1 Measurement and calculation of the density solid object with pycnometer
16 Ιουλ 2024 · Here’s a conversion table for density, illustrating how to convert between common units of density such as kilograms per cubic meter (kg/m³), grams per cubic centimeter (g/cm³), pounds per cubic foot (lb/ft³), and pounds per cubic inch (lb/in³): Conversion: 1 gram per cubic centimeter (g/cm³) = 1000 kilograms per cubic meter (kg/m³).
27 Μαΐ 2020 · Here is a table of density of common materials. It's easy to compare the densities of solids, liquids, and gases and construct a density column.
20 Ιουλ 2023 · Use the density from Table \(\PageIndex{1}\) "Densities of Some Common Substances" as a conversion factor to go from volume to mass: \[44.6\,\cancel{mL}\times \dfrac{13.6\,g}{\cancel{mL}}= 607\,g \nonumber \nonumber \]
