How much energy is released when 1.56 kg of ethanol 46.0 g mol freezes The heat of fusion of ethanol is 4.94 kJ mol?
To calculate the energy released when 1.56 kg of ethanol freezes, first convert the mass of ethanol to moles using its molar mass. Then, use the heat of fusion of ethanol to determine the energy released using the formula: Energy released = moles of ethanol x heat of fusion.
The molar heats of sublimation and fusion of iodine are 62.3kjmol and 15.3kjmol respectively calculate the molar heat of vaporization of liquid iodide?
It is a known fact : Molar heat of sublimation = molar heat of fusion + molar heat of vaporization so, molar heat of vaporization = molar heat of sublimation - molar heat of fusion Mv = 62.3 kJ/mol - 15.3 kJ/mol Mv = 47 kJ/mol.
The molar heat of fusion for water is 6.008 kJmol What quantity of heat energy is released when 253 g of liquid water freezes?
To calculate the heat released when 253 g of water freezes, first convert the mass to moles using the molar mass of water (18.015 g/mol). Then, use the molar heat of fusion to determine the total heat released. Therefore, 253 g of water is 14.05 moles (253 g / 18.015 g/mol) and the heat released is 84.5 kJ (6.008 kJ/mol * 14.05 mol).
What is the molar heat of fusion of water?
The specific latent heat of fusion of water is 334 kJ/kg. Ice melts at 0 degrees Celsius and boils at 100 degrees Celsius.
How much heat in kJ is required to melt 54.0 g of ice at 0 and degC into water at 0 and degC if and DeltaHfus for water 6.01 kJmol?
The first step is to convert the mass of ice to moles using the molar mass of water (18.015 g/mol). Then, use the molar enthalpy of fusion to determine the heat required to melt the ice. Finally, multiply the molar enthalpy of fusion by the number of moles of water to get the total heat required in kJ.

It is a known fact : Molar heat of sublimation = molar heat of fusion + molar heat of vaporization so, molar heat of vaporization = molar heat of sublimation - molar heat of fusion Mv = 62.3 kJ/mol - 15.3 kJ/mol Mv = 47 kJ/mol.
What is the Heat of fusion of ethanol?
4.931 kj/mol
What is the relation of the molar heat of fusion to the molar heat of vaporization?
Molar heat of fusion: the heat (enthalpy, energy) needed to transform a solid in liquid (expressed in kJ/mol). Molar heat of vaporization: the heat (enthalpy, energy) needed to transform a liquid in gas (expressed in kJ/mol).
How do you calculate the molar heat of fusion?
Use Einstein's Theory of Special Relativity
When 1661J of heat energy is added to 38.7g of ethanol C2H6O the temperature increases by 17.5 C calculate the molar heat capacity?
The molar mass of ethanol is 46.07 g/mol−1 so 38.7 g of ethanol would be 0.84 moles (strictly speaking gram∙moles). If 1661 J warms it up by 17.5 °C then the molar heat capacity would be about 112 J/mole/°C (or J/mole/K if you prefer those units). Note that heat capacity is a function of temperature, so the value is only correct for the temperature where the measurements were made.
