This requires use of the molar heat capacity formula. That means you need the specific heat of water and the molar mass of water. The molar mass of water is 18.0 g/mol. molarheatcapacity=(4.18Jmol∗K)(18.0g1mol) Multiplying that together you get: molarheatcapacity=75.2J/mol∗K...
Specific heat is defined as the amount of heat required to raise one unit of mass of the substance by 1 unit of temperature. Mathematically, it is the heat capacity of a substance divided by its mass. The formula for specific heat is: Here, c is specific heat and has units J/kg.K, ...
The gas constant for the mixture is calculated from the following formula: Equ 2.52R¯=R¯M¯ where: R¯ = effective gas constant kJ/(kgK) 2.6.6.3 Mean molar specific heat The mean molar specific heats can be calculated from: Equ 2.53c¯p=∑mx(M.cp)x Equ 2.54c¯v=∑mx...

Using the specific heat of water of 4.2 J/g/∘C , the heat of combustion formula gives us the molar heat of combustion for ethanol. So, 1g of ethanol gives -29.78 kJ of energy or, in molar mass, 1,370 kJ/mol. For other alcohols, values are: Methanol: -732 kJ/mol Propanol: -...
Molar specific heat of formation of a hydrocarbon CnHm in MJ/kgmole: (q¯f°)CnHm=−[n(393.5)+(m/2)(285.5)+HHVCnHm] 6. Molar specific enthalpy of formation of a compound at the standard reference state is the same as its molar specific heat of formation: (h¯f°)compound=(q...
Specific heat capacity is a property of a substance that tells the amount of energy needed to raise one gram of a substance by one degree Celsius. The values of these properties are related to the strength of their intermolecular forces.• Polar substances dissolve ionic or polar substances; ...
