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

### When n is not given

If the moles of gas is not given and not able to calculate, is it safe to assume that it is 1 mole?

If it states ideal gas, then yes it is safe to assume.

If you are referring to the q=nCm(Delta T) then usually it will give you specific heat or another value for C that you can plug into the equation q=C(Delta T) or q=mCs(Delta T) if it does not give you the moles.

If the question requires you to use moles, it will give you that information or the information necessary to find the number of moles. Is there a specific question which you may be referencing?
