Question

80cm3 of iron weights 624g.calculate the density of iron​

Answer 1

Given:

☛ volume of iron, V = 80 cm³

☛ mass of iron, M = 624 g

To Find:

☛ density of iron

Solution:

We know

=>> Density = Mass / Volume

=>> Density = 624 / 80

=>> Density = 7.8

Hence, The density of iron is 7.8 g/cm³

Answer 2

Answer:

the density of copper is 8.9g/cm³.find it's value in kg/m³
