How do you calculate heat capacity?
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 c of the substance?
The specific heat capacity of a substance is the amount of heat required to raise one gram of the substance by one degree Celsius. Water for example has a specific heat capacity of 4.18 . This means to heat one gram of water by one degree Celsius it would require 4.18 joules of energy.
What is C sub p?
Molar Heat Capacity (C_{p}) is the amount of heat needed to increase the temperature of one mol of a substance by one degree at constant pressure. It is expressed in joules per moles per degrees Kelvin (or Celsius) J/(mol K).
What is molar energy?
The molar heat capacity of a chemical substance is the amount of energy that must be added in the form of heat to one mole of the substance in order to cause an increase of one unit in its temperature. … The SI unit of specific heat is joule per kelvin per mole J⋅K^{−}^{1}⋅mol^{−}^{1}.

The specific heat (also called specific heat capacity) is the amount of heat required to change a unit mass (or unit quantity such as mole) of a substance by one degree in temperature.
How do you find the heat capacity of brass?
The heat is calculated from the equation Q = cp x m x ΔT The unit for cp is thus heat per unit mass per unit temperature. The value of cp does depend on the temperature. However for the small temperature range we are interested in it is a good approximation to regard cp as temperature independent.

How do you find KJ mol from J?
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).
