Density Lab

Brief Descirption

Learn how to use measuring beaker, graduated cylinder, and balance scale to measure the density of a given substance.

Equation: `ρ = m/V`

Density (`ρ`) : units `kg//m^3`, Mass (`m`) : units `kg`, Volume (`V`) : units `m^3`
Specific Gravity (Relative Density) - SG
SG is a dimensionless unit defined as the ratio of the density of a substance to the density of water.
`SG = ρ/ρ_(H_2O)` `(ρ_(H_2O) = 1.00 times 10^3\ kg//m^3)`
