Delta S = nC In (T2/T1)

[Samantha Chung 4I]

In the textbook, the equation for delta S = C In (T2/T1), but in Dr. Lavelle's formula booklet, the equation is S = nC In (T2/T1). Im confused about what equation to use?

You should use the equation that has the n in it. The other one is assuming that if you have an amount other than 1 mole you will account for this and multiply by that as well

[Karishma_1G]

The C in the equation from the textbook is most likely referring to the heat capacity, whereas the C in Dr. Lavelle's equation is the molar heat capacity (that's why you have to multiply by the number of moles)
