You can take the shortcut when everything is in L and use L as mols.
2C2H2 + 5O2 ==> 4CO2 + 2H2O
L oxygen needed = L C2H2 x (5 mols O2/2 mols C2H2) = 25L x 5/2 = ?
Acetylene(C2H2) burns in oxygen to form carbon monoxide and water. How many liters of oxygen(at STP) are needed to burn 25.0 L of acetylene (at STP)?
