Question

The mass of an empty bucket of capacity 10 litresis 1kg Find its mass when
completely filled with a liquid of relative density 0.8​

Answer 1

Density =mass/volume

Density of empty bucket=1/10=0.1

As density is directly proportional to mass

0.1=1kg

0.8= x

by cross multiplication

0.8=x(0.1)

x=0.8/0.1

x=8 kg
