(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A sample of an unkown material weighs 200 N in air and 150 N when immersed in water. What is the specific gravity of this material?

2. Relevant equations

specific gravity = (density/density of water)

density of water is 1000 kg/m^3

3. The attempt at a solution

I don't even know where to start. All my text book says is the specific gravity of a substance is the ratio of its density to the density of the water at 4 degrees C. I don't know how to relate this to an equation or begin to solve it.
