This is just part of the solution. Once you have the number of mol of HCl in 25cm3 of solution, scale it up to 500cm3 proportionally. That would be the amount dissolved originated from the gas.
From there, work out mol of XCl2. With mol and mass, you can find Mr of XCl2. You should know what to do next then...
