1) The Specific Heat Capacity at 25°C of Gold is 0.129 / (g°C) a) What is the molar Specific Heat Capacity of Gold in J/(mol °C)​

25.4 J/mol

Explanation:

The specific heat of any substance is referring to the amount of energy required to raise 1 gram of that substance 1 degree kelvin. Molar heat capacity is referring to the amount of energy required to raise 1 mole of that substance 1 degree kelvin. So in order to solve for molar heat capacity of gold we must convert from grams of gold to moles of gold.

( 0.129 J /g) ( 196.97 g/ m o l ) = 25.4 J m o l

196.97 is the molar mass of gold which can be found on the Periodic Table of Elements. Because grams are located on both sides of the denominator they cancel out leaving us with our new units of J/mol.

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
