Question

a piece of iron when immersed in water taken in Eureka can displaces 25 ml of water its mass is 195 gram find the density of iron in KG metre per cube​

Answer 1

Given:

The volume of water displaced = 25 ml

The mass of iron piece = 195 gm = 0.195 gm

To Find:

The density of iron in Kg/m³.

Calculation:

- According to Archimede's principle:

The volume of iron cube = The volume of water displaced

⇒ The volume of iron cube = 25 ml = 25 × 10⁻⁶ m³

Density = Mass/Volume

⇒ ρ = 0.195/25 × 10⁻⁶

⇒ ρ = 0.0078 × 10⁶

⇒ ρ = 7800 kg/m³

- So, the density of iron is 7800 kg/m³.
