      I did that and I got BaCl2, I was just wondering if there was an easier way than doing trial and error with all the possible answers.

      Thanks!

        Subtracting barium from the final molar mass.get you ~70 g/mol, ie the mm of Cl x 2. I double checked the other options but you can definintely rule out the bromide salt based on that
