## What does n represent?

Volume: $\Delta S = nR\ln \frac{V_{2}}{V_{1}}$
Temperature: $\Delta S = nC\ln \frac{T_{2}}{T_{1}}$

### What does n represent?

In the two equations delta S = n Cv ln(T2/T1) and delta S = nRln(v2/v1), what does n represent? Please be specific in terms of whether n represents products or reactants.

The value of n represents the number of moles of the substance in the problem. Usually in these types of problems, the moles will not change as it's only the temperature, pressure, or volume that is changing.

n represents the number of moles in the problem. If we are given the mass in grams, we would convert to moles by dividing by the molar mass.
