> The isothermal compressibility $\kappa_t$ of a substance is defined as $$ \kappa_t = -\frac{1}{V} \left ( \frac{\partial V}{\partial P} \right )_T $$ Obtain an expression for the isothermal compressibility of an ideal gas. (PV = RT) in terms of p.
I believe that the ideal gas law equation may be a typo (i.e. PV = nRT). Anyways, I have first set $P = RT/V$ and then taken $P_{VT}$ (partial derivatives). Is this the right way to go?
