- 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.Give typed full explanation A stock solution of lithium phosphate (Li3PO4, MM= 115.794361 g/mol) is prepared by dissolving 295.8 g Li3PO4 in deionized water to a final total volume of 1.000 L. Suppose a 1.000-mL aliquot is taken from this stock solution and transferred to a new container to which deionized water is added until the total volume is 50.00 mL. A new 1.000-mL aliquot is taken from this 50.00 mL solution and transferred to a third container to which deionized water is added until the total volume is 25.00 mL. Calculate the number of individual lithium ions (Li+) in the final 25.00-mL solution. Note that lithium phosphate is a strong electrolyte that completely dissociates in water (note that (aq) means the species is a solute in an aqueous solution): Li3PO4 (aq) 3 Li+ (aq) + PO43– (aq) Report your answer to two significant figures. Use scientific notation. Example: 1.0*10^23 (this notation means 1.0 1023)Pls give with reason, the type and name of the reaction.
