Question

1. A 12.5843g sample of zrbr4 was dissolved and after several steps all of the combined bromine was precipitated as ArBr. The silver content of AgBr was found to be 13.12160g Assume the atomic masses of silver and bromine to be 107.868 and 79.904.what value was obtained for the atomic masses of Zr from the experiment?
This is almost the same as the MO2/M2S3 problem but I would convert 12.13160 g Ag to the mass of AgBr. Post your work if you get stuck.
