In order to determine the formula of CoCly.xH;0, a student heated 0.476 g of hydrate. The mass of residue was 0.26 g. What is the approximate value of (x)? (F.Wt. of CeCl;= 129.93 g/mol, F.Wt. of H;O= 18 g/mol). L 6 II. 5 IV 2 III 3

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)
