The mass of sample = 10 g
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
The unit of density can be expressed in g/cm³ or kg/m³
Density formula:
[tex]\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}[/tex]
ρ = density , g/ml
m = mass , g
v = volume , ml
Density is 5 g/ml and sample is 2 ml,so :
ρ = 5 g/ml
V = 2 ml
The mass :
[tex]\tt mass=\rho\times V\\\\mass=5~g/ml\times 2~ml\\\\mass=\boxed{\bold{10~g}}[/tex]
