The specific heat of gold is 0.129 J/g·°C. What is the molar heat capacity of gold?

Question

Quizplus · Accepted Answer

The molar heat capacity of a substance is the amount of heat required to raise the temperature of one mole of the substance by 1 degree Celsius. It can be calculated using the formula:

Cp = (n × Cv)

where Cp is the molar heat capacity, n is the number of moles, and Cv is the specific heat capacity in J/g·°C.

To find the molar heat capacity of gold, we need to convert its specific heat capacity to J/mol·°C. We can do this by multiplying the specific heat capacity by the molar mass of gold, which is 196.97 g/mol:

Cv = 0.129 J/g·°C × 196.97 g/mol = 25.4 J/mol·°C

Therefore, the correct answer is choice C – 25.4 J/mol·°C.

The Specific Heat of Gold Is 0
