I am attempting to do a PCM for melting and solidifcation of a eutectic tin lead solder, and am curious as to my material property accuracy.
My understanding is that the standard state enthalpy is your molecular weight [kg/kmol] multiplied by the latent heat [J/kg] to get the appropriate enthalpy [J/kgmol]. Is this accurate here?
Additionally, I have the MW of 63Sn-37Pb as ~320 kg/kmol by simply adding the two atomic weights of both Tin (118.71 ) and Lead (207.2). Is this a good ballpark estimation? Am I missing anything critical here?

So 0.63*118 + 0.37*207 = 150 should be the average molar mass of the alloy.
