Question

density of copper is 8900 kg/m³ what is the mass of 10cm³ of copper?​

Answer 1

$density = \frac{mass}{volume}$

1m³ of copper has mass = 8900 kg

=> 1000000cm³ haa = 8900kg

=> 10 cm³ copper has mass =

$\frac{8900}{1000000} \times 10kg \\ = .89kg$

Answer 2

Answer:

89 g.

Step-by-step explanation:

Density of copper =8900 kg/m³

= 8900

            g/cm³  [ ∵ 1 g/cm³ = 1000 kg/m³]

  1000

=8.9 g/cm³

Volume of copper = 10 cm³

As, Density =   Mass    

                      Volume

or, Mass = Density × Volume

∴ Mass of copper = 8.9 g/cm³ of copper is 89 g

Hence, the mass of 10 cm³ of copper is 89 g.
