Entropy moles

In a particular problem on the homework, it gave the values of delta s subscript m, when trying to calculate gibbs free energy, (specifically the change in entropy within the equation) however the chemical equation had 2 moles of it so the solution divided the given delta s values by 2. why is that?

This is because Delta S Subscript M is given per mole so you must always divide by the number of moles of the substance to get it to be per 1 mole. :)
