The density of an object = 5 g/ml
Density is a quantity derived from the mass and volume Â
Density is the ratio of mass per unit volume Â
The unit of density can be expressed in g/cmÂł or kg/mÂł Â
Density formula: Â
[tex]\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}[/tex]
Ï = density Â
m = mass Â
v = volume Â
Mass = 50 g
Volume of the object =
[tex]\tt 40-30=10~ml[/tex]
So the density :
[tex]\tt \rho=\dfrac{50}{10}\\\\\rho=\boxed{\bold{5~g/ml}}[/tex]
