I need help with Stoichiometry Mapping and solving using the "line bar" method

Cl2P4(s)+6Cl2(g) --> 4PCl3(g)
How many mL of PCl3 can be produced by the reaction of so g of Cl2(g)

    I don't know the line bar method, at least by that name. I have used ICE charts and that may be the same thing.To find mL you need the density too.
    First, the equation isn't balanced. It should be
    Cl2P4(s) + 5Cl2(g) ==> 4PCl3(g)
    Convert 50 g Cl2 to mols. mol = grams/molar mass = ?
    Now convert mols Cl2 to mols of the product using the coefficients in the balanced equation.
    mols Cl2 x (4 mol PCl3/5 mol Cl2) = ?
    Then convert to g. g = moles x molar mass.
    You use the density, not posted, to convert to mL. mL = mass/density.
