Question

The level of water in a measuring cylinder rose to 90cm³ mark when a piece of stone whose mass is 10 g was dropped in the measuring cylinder. the initial volume of the water as 50 cm³ calculate the density of the rock. show working ( means show your calculations of how you solved it :] )
pleaae this is under science but it's not giving me that option so i choose chemistry

  • Answer:

    o.25g/cm3

    Explanation:

    initial volume(V1)= 50cm3

    final volume(V2)= 90cm3

    volume of stone(i.e, level of water displaced)= V2 - V1

    = 40cm3

    mass of stone= 10g

    density= mass/volume

    = 10g/40cm3

    = 0.25g/cm3
