Enthalpy conversion
WebDec 26, 2016 · 1. You need to know the molar mass M ( g / m o l) of the material (substance). Say the Enthalpy in J / g is H w, then the Enthalpy in J / m o l is H M, with: H M = H w × M. Divide by 1000 to convert to k J / m o l. If the material is not a pure substance (i.e. a mixture) then you need to calculate a molar average for M of the material. WebTemperature, humidity and pressure inputs in are converted to SI values for calculations of volume, density and enthalpy. The results are converted back to IP units for display. ...
