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
5 g piece. To do this, we divide the mass of gold by its molar mass. The molar mass of gold is 197.0 g/mol. So, the number of moles of gold is: 28.5 g / 197.0 g/mol = 0.1447 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?
12.0 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?
