Question

The mass of an empty bucket of capacity 10 liters is 1 kg. Find its mass (in kg) when completely filled with a liquid of relatively density 0.8.

Answer 1

Given relative density of liquid = 0.8

Density of liquid = 800 kg/m³

Volume of bucket = 10 liters  = 10× 10⁻³ m³

Mass of the bucket = 1 kg

We know density = mass/volume

mass = density × volume

m = 800 × 10× 10⁻³ = 8 kg
