Question

The heat lost or gained by a system is related to its temperature change by a property called its heat capacity. The molar heat capacity of metals at or above room temperature equals 24.92 J K-1mol-1.

The temperature of a block of copper metal (molar mass 63.55 g mol-1) fell by 9.56 K when the copper block released 23.6 J of heat. What is the mass of the copper block?
