1 mole C3H6 = 42 g
1 mole C3H8 = 44 g
1 mole H2 = 2 g
From the balanced equation, 2g H2 is required to form 44 g C3H8.
Amount of H2 required to form 18 g C3H8 = 18 g C3H8 x 2 g H2 / 44 g C3H8 = 0.82 g
Now, from ideal gas equation,
PV = nRT
=> V = nRT/P = (0.82/2) x 0.0821 x 297 / (745/760)
=> V = 10.2 L
