Cl2P4(s)+6Cl2(g) --> 4PCl3(g)

How many mL of PCl3 can be produced by the reaction of so g of Cl2(g)

**DrBob222**, Thursday, March 8, 2012 at 11:43pmI 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.
