## Homework Statement

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?

## Homework Equations

Buoyant force = mass*gravity

Buoyant force = (Density of fluid)*(volume of iron block)*(gravity)

## 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.
