Density chemistry units
WebThe unit for volume is a unit derived from the SI unit of length and is not a fundamental SI measurement. If two water samples have different volumes, they still share a common measurement: the density. Density is another measurement derived from SI basic units. The density of a material is defined as its mass per unit volume. WebSep 23, 2024 · Notice that density is defined in terms of two dissimilar units, mass and volume. That means that density overall has derived units, just like velocity. Common units for density include g/mL, g/cm 3, g/L, kg/L, and even kg/m 3. Densities for some common substances are listed in Table 2.6.1.
