Is molar heat capacity the same as specific heat?

Molar heat capacity is a measure of the amount of heat necessary to raise the temperature of one mole of a pure substance by one degree K. Specific heat capacity is a measure of the amount of heat necessary to raise the temperature of one gram of a pure substance by one degree K.

What is the specific heat of water in J kg K?

4184 joules
The SI unit of specific heat capacity is joule per kelvin per kilogram J⋅kg−1⋅K−1. For example the heat required to raise the temperature of 1 kg of water by 1 K is 4184 joules so the specific heat capacity of water is 4184 J⋅kg−1⋅K−1.

What is the specific heat capacity of water in J kg C?

4 200 Joules per kilogram per degree Celsius

The specific heat capacity of water is 4 200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4 200 J to raise the temperature of 1 kg of water by 1°C. Lead will warm up and cool down fastest because it doesn’t take much energy to change its temperature.

Accepted book enthalpies are in the units kJ/mol. Simply convert J to kJ by dividing by 1000. Since 1 kJ=1000 J. You would use the moles of the product.

How do you convert joules to J Mol?

Divide the number of joules released in the reaction by the known joules per mole constant for that type of reaction. For example if a reaction between sodium hydroxide and water releases 30 000 joules of energy divide 30 000 by 55 200 to get . 54 moles.

How do you convert J to KJ mol?

Re: How to convert kJ/mol to J

Answer: Cancel out the 1/mol unit by dividing by the Avogadro constant. Then convert kJ to J by multiplying the kJ value by 1000 (because of the conversion factor 1 kJ = 1000 J).
