Calculate or determine experimentally?

I would like to calculate but I do not know how. I know only the total weight of the solution. How to wrap up? Please help

You can weight before and after passing the HCl gas.

The difference guide you to the mass of HCl. This you can calculate as w.w or also w.v., if you know the volume.

This is pretty ambiguous. Calculate from what kind of data?
