Assume we have three states of saturated vapor R-134a at +40 C, 0 C, and - 40 C. Calculate the specific volume at the set of temperatures and corresponding saturated pressure assuming ideal-gas behavior. Find the percent relative error = 100(v-vg)/vg with vg from the saturated R-134a table. How do I approach this problem?

what is R-134a? i'm assuming that you would use the ideal gas law, PV=nRT
