Aight can anyone help me out with this webassign problem?

A solution is found to be X% by weight AlCl3. What is the concentration of the Cl1- ion expressed in ppm?

1. I started off by X% * 10^6 to get my grams of AlCl3
2. divided by it's molar mass to get mols of AlCl3 per 10^6 grams of solution
3. multiplied by 3 to get my moles of chlorine
4. multiplied by 35.45 (mass of Cl) to get grams per 10^6 of solution

The answer is wrong, and much thanks for anyone who can explain what I am doing wrong.

um, to be fair he's asking for someone to explain what he did wrong, not the straight up answer.
