In the formula for delta Srxn, we have the sum of the products of Sm minus the sum of the reactant of Sm.

I'm confused about what the "m" of Sm is.

The "m" in Sm stands for molar, so Sm means molar entropy.

To find the change in entropy, subtract the molar entropy of the products from the reactants.

the m stands for molar or mass depending on what you are given and what you need to find. If you need to find over kJ/mol and you were given mass you would need to convert to moles. The reason why there is an m is mostly because S is extensive.

m is just molar! so Sm is molar entropy
