What is the apparent weight of a 25kg lead block submerged in the dead sea? (density of dead sea is 1240kg/m3)

    calculate the volume of the lead block
    volume=mass/density

    now calculate the mass of water that is displaced by that volume.

    mass=densitywater*volumeblock

    now apparent mass in water=
    mass lead-massdisplacedwater

    apparent weight=apparentmass*g
