Suppose you have three objects of equal mass. The first object has a volume of 5 cm3 and is made of a material of density 2 g/cm
liubo4ka [24]

Answer:

2 g/cm³

Explanation:

m = Mass of object

v = Volume

ρ = Density

When ρ = 2 g/cm³ , v = 5 cm³

\rho=\frac{m}{v}\\\Rightarrow m=\rho v\\\Rightarrow m=2\times 5\\\Rightarrow m=10\ g

All the objects have same mass, which is 10 grams

When v = 5 cm³

\rho=\frac{m}{v}\\\Rightarrow \rho=\frac{10}{5}\\\Rightarrow \rho=2\ g/cm^3

Density of third object is 2 g/cm³
