If kilogram $( kg)$ is used as the unit of weight, and litre $( l)$ is used as the unit of volume, then find the unit of density, given by the following expression.Density$=\frac{Weight}{Volume }$
A. $l/kg$
B. $kg/l$
C. $kg\times l$
D Cannot be determined

Solution:

If kilogram $( kg)$ is used as the unit of weight, and litre $( l)$ is used as the unit of volume, then the unit of density is $kg/l$.

Thus, option $( C)$ is correct.
