A35.8 g sample of cadmium metal was melted by an electric heater providing 4.66 J/s of heat. If it took 6.92 min from the time the metal began to melt until it was completely melted, what is the heat of fusion per mole of cadmium?
This is a pretty creative problem.
of cadmium are melted.
of heat were required, hence,
is the heat of fusion for cadmium, per the data under analysis.
