A piece of stainless steel which is having the specific heat = 0.50 Jg^-1c^-1 is transferred at 23.6C^o from an oven at 191C^o into the 125 mL of water. The water temperature rises to 50.5C^o .
1. Calculate the mass of the steel and articulate your answer using the two significant figures.
2. Explain how precise is this method of mass determination?
