Answer:
5.13 kg/L
Explanation:
The units for density are mass divided by volume. This means that for an expression to be a measurement of density it would need to have an unit of mass in the numerator, and an unit of volume in the denominator.
With that in mind, kg is a unit of mass, and L is a unit of volume, so any positive number followed by "kg / L" is a measurement of density.
