The mass of a density bottle is 25g when empty , 50g when filled completely with water 365g when filled completely with mercury. Find the density of mercury.

mass of bottle=25g
mass of mercury=365-25=340g=0.340kg
mass of water=50-25=25g=0.025kg
first calculate volume
density=mass/volume
we know mass of water,density of water
volume =mass/density=0.025/1000=25×10-6m3
now we find the density of mercury
density=0.340/25×10-6=13600kg/m3
