Sometimes the unit J/g is used. In that case, it is referred to as the heat of vaporization, the term 'molar' being eliminated. The molar heat of vaporization for water is 40.7 kJ/mol. To get the heat of vaporization, you simply divide the molar heat by 18.015 g/mol. dave and buster new york cityWebMar 15, 2015 · Assuming that the standard state is the usual one, then p ∘ is one bar, which is equal to 750 mmHg. This is what we have assumed in step 1. If that is the case, then p = 0.176 p ∘ = 0.176 ⋅ 750 mmHg = 134 mmHg. How would it know that this unitless quantity is atm and not pascal or mmHg?
