Change in specific enthalpy for saturated water vapor compressing at constant temperature

[t3rom]

Homework Statement

What is the change in specific enthalpy if saturated water vapor at 100 bar compresses to a pressure of 150 bar? The temperature is constant.

Homework Equations

None

The Attempt at a Solution

I used this equation to solve the problem: delta h = delta e + p * delta v
I found the value of delta e and delta v from steam tables. The answer I'm getting is 190049 kj/kg which is incorrect. Any help would be greatly appreciated, TIA!

I got it. Had to lookup values of enthalpy at 100 bar and 150 bar then take the difference of them.
