What volume of iron would be needed to balance a 30 cm3 sample of copper ? ( density of iron is 7.87 g/cm3 and density of copper is 8.96 g/cm3)

Explanation:

Density of an object is defined as the mass occupied per unit volume. “Density” is represented by “ρ”. Mathematically, where, “m" mass of an object and "v" is volume of an object.

Given that,

Step: 1

To find the mass of the copper:

Mass of the copper is 268.8 kg.

To balance the weight of the copper 268.8 kg = weight of the iron the volume required is

Step: 2

heat the gas and measure the pressure
