Take 1 liter of 12 M HCl
Weight solution= 1180 g
weight HCl = 36.5x12=428 gm
weight water = 752 gm
Now figure it out.

You can't do either of those calculations with the information given. Molality is moles of solute/kilograms of solvent. You don't have either. Same with weight percent. Weight percent is a percentage of a certain element in a compound.
