A K2SO4 solution is prepared by weighing out a certain amount of the pure solid reagent,dissolving it to 500.0 mL in a volumetric flask. An aliquot was taken from this solution.of 25.00 ml and diluted to 500.0 ml. An aliquot of 5.00 was taken from this new solution anddiluted to 50.00 ml. A chemical analysis of this new solution showed a 0.100%(w/v)in K+. Calculate the weight of the pure solid K2SO4 used for the preparation of the original solution.and its concentration in each volumetric flask. The answer is 2.23x10^2g
In this problem I thought of using v/n=v/n or mv=mv, but neither get the correct answer. mv=mv yields 1.4 and v/n=v/n yields 0.4. Am I doing these calculations wrong, or am I doing the wrong type of calculation in the first place?

A sample of steel (0.506 g) was digested in acid and the solution made up to 100 cm3 with deionised water. Aliquots (25.0 cm3) of this solution were transferred into two volumetric flasks (100 cm3) labelled A and B. Flask A was made up to volume with deionised water. To flask B was added 10.0 cm3 of a 260 ppm standard solution of Mn2+ which was then also made up to volume with deionised water. The following absorbance results were obtained: Solution A = 0.356, Solution B = 0.578. Use these results to calculate the percentage (% w/w) of manganese in the steel sample.

There is actually something im confused about, when you calculating V0 for S0=200uM --> V = 0.48*200/ 2.42 + 1 Why are you only using the S0 value=200uM one place in the equation and then using the S0 value from given data the second place in the equation? Shouldnt S0 be 200 uM both places in the equation?
