ok. so buoyant force=mg-tension, and then density x volume x gravity= m x g -T? it dosent give the mass of the block though

An iron anchor of density 7870 kg/m cubed appears 200N lighter in water than in the air. a) what is volume of anchor? b) what is its weight in the air? I set volume equal to buoyant force/ density x gravity

A styrofoam block with a volume of 5.00cm cubed and a density of 45 kg/m cubed is submerged in an unknown liquid tethered from floating to the surface by a rope fixed to the bottom of the container. the tension in the rope measures 3.63x10^-2 N. Determine density of unknown liquid. I set...
