Step 1
5°C Given final temperature, Tf = 328.3°C ΔT = Tf - Ti ΔT = 328.3°C - 22.5°C ΔT = 305.8°C Show more…

The specific heat of solid copper is $0.385 \mathrm{J} / \mathrm{g} \cdot^{\circ} \mathrm{C}$ ). What thermal energy change occurs when a $35.3 \mathrm{g}$ sample of copper is cooled from $35.0^{\circ} \mathrm{C}$ to $15.0^{\circ} \mathrm{C} ?$ Be sure to give your answer the proper sign. This amount of energy is used to melt solid ice at $0.0^{\circ} \mathrm{C} .$ The molar enthalpy of fusion of ice is $6.01 \mathrm{kJ} / \mathrm{mol} .$ How many moles of ice are melted?
