could you please solve this a and b?

below is the steam table, which is needed to solve this problem

Problem 2 a) Calculate the second virial coefficient of water at 200C using only data from the steam tables. b) Use the truncated virial equation along with the second virial coefficient calculated above to estimate the volume of water at 200C,14 bar. How does this value compare with the volume obtained from the steam tables? Discuss this comparison. Table E-1: Saturated Steam. cont. (part 2 of 2 )
