How many moles of hydrogen gas are required to react completely with 807 L of ethylene (C2H4) according to the following reaction at 0oC and 1 atm?

hydrogen (g) + ethylene (C2H4) (g)---> ethane (C2H6) (g)

Should I use the ideal gas law here?

• Chemistry -

You may but you also may use a shortcut since all of the materials are gases. Just pretend L are the same as mols; therefore, 807 L x (1 mol H2/1 mol ethylene) = ? L H2 required.
