A 28.5 g piece of gold is heated and then allowed to cool. What is the change in temperature (°C) if the gold releases 0.226 kJ of heat as it cools? The molar heat capacity of gold is 25.4 J/mol･°C.

Step 1
First, we need to find the number of moles of gold in the 28.5 g piece. The molar mass of gold is 197 g/mol. Number of moles = (mass of gold) / (molar mass of gold) Number of moles = (28.5 g) / (197 g/mol) Show more…

Gold has a specific heat of $0.129 \mathrm{~J} / \mathrm{g} \cdot{ }^{\circ} \mathrm{C}$. When a $5.00-\mathrm{g}$ piece of gold absorbs $1.33 \mathrm{~J}$ of heat, what is the change in temperature?
5.00 J of heat is added to 10.00 g of gold which is initially at 25°C. The heat capacity of gold is 25.41 J / (mol • °C). What would be the final temperature of the gold?
