## How can I find the mass of a steel ball given its radius ...

2008-6-27 The radius of the steel ball is r = 2cm = 0.02m and its specific heat is c = 0.486kJ/kgK Analyzing the units of these given values, I thought simple unit analysis would work. For example, 1/c would give units of kgK/kJ. The volume of the ball is v = (4/3)pi(r)^3 which has units of m^3. I'm having a difficult time trying to relate these things and manipulate them to just get the mass of this ball.
