A density bottle has a mass of 35g when empty, 85g when filled with water and 75g when filled with kerosene. Calculate the density of kerosene in g/cm3.

  • Physics i.e science -

    assume the volume is V

    density water=85/V
    V=85/densitywater
    density kero=75/V

    density kero=75*densitywater/85

    but density water=1gm/cc
    so do the figuring.

  • Physics i.e science -

    YES

  • Physics -

    mass of bottle=35
    mass of water=85-35=50g
    mass of kerosene=75-35=40g
    therefore,density of kerosene=
    mass of kerosene/mass of water=
    40g/50g= 4g/5g=1.15

    ANS=1.15 g/cm3
