A chemist dissolved 0.08346g of SrCl2 (FW 158.53) and treated it with excess AgNO3 (FW 169.87) to precipitate 0.143g of AgCl (FW 143.32). In his time, the atomic mass of Ag was known to be 107.8 and that of Cl was 35.4 From these values, find the atoimic mass of Sr that the chemist would have calculated.
A saturated Na₂CO₃ solution isprepared, and a small excess of solid ispresent (white pile in beaker).
