1. The problem statement, all variables and given/known data A 2.0 kg iron block is suspended from a spring scale and is submerged in a fluid of unknown density. The spring scale reads 2.55 N. What is the density of the fluid? 2. Relevant equations Buoyant force = mass*gravity Buoyant force = (Density of fluid)*(volume of iron block)*(gravity) 3. The attempt at a solution 2*9.81=(density)*(volume)*9.81 I can't figure out how to get the volume to solve for the density.
