A sample of a compound of Cl and O reacts with an excess of H2 to give .233g of HCl and .403g of H2O Determine the empirical formula of the compound

Can anyone help explain how to solve this problem?

Thanks

ALL the Cl and O in the products come from the unknown compound. This fact can be used to determine the amount (in moles) of Cl and O present in that compound.

Please show some of your thoughts/ working if you require more assistance!
