The mass of density bottle of volume 50cm3 is 10g when empty. Aluminium turnings are poured into the bottle and the total mass is 60g. Water

Question

The mass of density bottle of volume 50cm3 is 10g when empty. Aluminium turnings are poured into the bottle and the total mass is 60g. Water is then added into the turnings till the bottle is full. If the total mass of the bottle and its contents is 90g, calculate the density of the aluminium turnings.

    • Total mass of the bottle = 90gm.
    • Total Volume of the bottle = 50cm3

    Total density = T. mass / T. Volume.

    = 90/ 50

    = 1.8 gm/ cm3

    Now,

    Mass of Water = 90 – 60

    = 30 gm.

    • Volume = 50cm3

    Density = Mass/ Volume

    = 30/ 50

    = 0.6 gm /cm3

    Now,

    Density of Aluminium = 1.8 – 06

    = 1.2 gm/ cm^3
