Density is $\frac{Mass}{Unit Volume}$ $"Mass"/"Unit Volume"$ ; relative density is the density compared to a reference substance (usually water) under standard conditions.

Explanation:

$Density, ρ$ $"Density, "rho$ $=$ $=$ $\frac{Mass}{Volume}$ $"Mass"/"Volume"$ , and usually is quoted with units $g \cdot m L^{- 1}$ $g*mL^-1$ or $g \cdot c m^{- 3}$ $g*cm^-3$ . Relative density or specific gravity ( https://en.wikipedia.org/wiki/Relative_density) is the density compared to a reference substance, that is water, which has a density of $1 \cdot g \cdot c m^{- 3}$ $1*g*cm^-3$ ; the relative density is thus a dimensionless quantity. If relative density is $>$ $>$ $1$ $1$ , the object should sink; if relative density is $<$ $<$ $1$ $1$ , the object should float. Why?
