Question

A bottle full of water has mass of 90g when full of mercury its mass 720g.if the mass of the empty is 40g calculate the density of the mercury

Answer 1

density = mass/ volume

mass of empty bottle=25g

mass of bottle filled with water=50g

mass of liquid =25g

volume of liquid=25ml

volume of mercury=25ml

mass of mercury=365−25=340g

density of mercury=340/25=13.6 g/cm3
