(Concentration) You are tasked to prepare 300.000 ppb of a sodium carbonate standard for a titrimetric analysis. If you need to prepare 1000.00 (±0.06) mL of this solution, how much (in grams) solid, pure Na2CO3 are you supposed to dissolve? What absolute uncertainty is associated with your mass measurement if the prepared solution has a 0.1% percent relative uncertainty? Write your answer using the appropriate number of digits. Note that the formula mass of Na2CO3 is 105.9888 g/mol with negligible error. Assume that instrument precision is not a limitation in your lab. (absolute error)

A sample of an iron ore was prepared for Fe3+ analysis as following: 3.4g of the sample was added anddissolved in acid environment then diluted to 250 mL using volumetric flask. After that, 10 mL of the resultingsolution was transferred by pipet to a 50-mL volumetric flask and continue to be diluted. The scientists foundout that this solution gives the concentration of Fe3+ as 2.3 mg/L. Find the weight percentage of Fe3+ in theoriginal sample.
