Question

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
