Question

If a 0.688 mole sample of silver at 19.6°C absorbs 1.162 kJ of heat, what is the final temperature in C?

Answer 1

1.162 kJ = 0.688 mol x specific heat x (Tf-19.6)

Solve Tf after substituting specific heat. Note that must have units of kJ/mol; otherwise you must change kJ or mols (or both).
