Molar heat of vaporization is defined as the heat absorbed by one mole of substance to convert from liquid to gas.
<h3>How do you calculate the heat of vaporization?</h3>The formula used to calculate the heat of vaporization is:
Where,
Q = Amount of Heat
n = number of moles of a substance
molar enthalpy of fusion
Now, to calculate the moles of methane:
Moles = 3.425 mol
Now, 1 mol of methane absorbs = 8.53 KJ
3.425 mol of methane absorbs =
Thus, the energy is absorbed till the methane vaporizes at its boiling point is 29.1 KJ.
