A gas at 350k...

Question

A gas at 350k and 15 bar has molar volume 20 percent smaller than that for an ideal gas under the same conditions. The correct option about the gas and its compressibility factor (Z) is (1) Z >1 and attractive forces are dominant (2) Z >1 and repulsive forces are dominant (3) Z <1 and attractive forces are dominant (4) Z <1 and repulsive forces are dominant
