An experiment was conducted to determine the specific heat of platinum. It was determined that 158.8 Joules of heat were required to increase the temperature of a 50.0 gram sample of platinum from 20.0 oC to 45.5 oC. Based on these experimental results calculate the specific heat (J/g⋅⋅oC) of platinum.
A 36.7 g sample of ethanol (C2H5OH) is burned in a bomb calorimeter containing a certain mass of water.
