If the initial volume of the ethane gas was 150L, what is the final volume of the products?

the reaction is C2H6----- C2H4 + H2

PV = nRT

Presumably (you haven't told us this) you kept P and T the same. What happened to n, the total number of molecules, and what has to happen to V?

You have a 1:1:1 mole ratio among reactants and products. If the temperature and pressure are returned to the initial conditions after the reaction is complete, you will form 150 liters of C2H4 and 150 liters of H2.
