Difference between 2 delta S equations?

Postby JeremyPark14B » Thu Feb 07, 2019 4:57 pm

In the textbook, the equation for delta S with given temperature change is Delta S = C x ln(T2/T1)

However, in the answer book, the equation Delta S = n x C x ln(T2/T1) is used.

Why is n neglected? Thank you for your time.

The book is a little inconsistent with their variables, but if you look at the example following the formula, they do use ΔS = nCln(T2/T1). So I'm just guessing they combine the n with C in the book, but both ultimately do use ΔS = nCln(T2/T1).
