The heat capacity of 5.00 g of gold is $0.640~J$
The heat capacity is the amount of heat required to raise the temperature by $1~ C^{\circ}$. We can find the heat capacity of 5.00 g of gold: $Q = m~c~\Delta T$ $Q = (5.00\times 10^{-3}~kg)(128~J/kg~C^{\circ})(1~C^{\circ})$ $Q = 0.640~J$ The heat capacity of 5.00 g of gold is $0.640~J$.
