Explanation:
Total mass =200g
Mass of beaker (beaker weighs when empty) =120g
Density of the kerosene is 800kg/m3
Mass of kerosene =Total mass-mass of the beaker
=200-120g
=80g
The formula for the density is
Density of kerosene =Mass/volume
From this formula we can find the volume of kerosene
Mass/density =Volume of kerosene
80/0.8 =100ml
Volume of kerosene is 100ml
So the volume of the kerosene is 100ml
