How to solve for molar heat capacity

WebOct 24, 2024 · Conclusion. The molar heat capacity of liquid water is 4.184 J/mol·K. This value is based on the specific heat capacity of water (4.184 J/g·K) and the molar mass of water (18.01528 g/mol). The molar heat capacity is a measure of the amount of heat required to raise the temperature of one mole of a substance by one Kelvin. WebNow that you have gathered all of the necessary data, you can calculate the specific heat capacity of the metal using the following equation: Specific heat capacity = (Heat added) / …
