Title: Carbonate lab question...
Post by: sandiegofan328 on September 23, 2018, 07:54:25 AM
I know that my molarity of Calcium Chloride is 0.40M but and am needing to find the mass percent of the carbonate in an unkwn carbonate salt. I have no clue where to start with this one...  ???

To less information like volume of the 0,4 m CaCl2 solution, mass of the unknown carbonate,probably mass of the calciumcarbonate (calculated from the calciumchloride).
Chemical reaction formula.

You have still not given us enough information, I have no idea what you are asked to do.
