Mass used to prepare 5.0 g/L sodium sulfate solution
Mass used to prepare 5.0 g/L sodium sulfate solution: 0.495 g <br/>Mass
used to prepare 0.025 M sodium sulfate solution: 0.329 g
Mass used to prepare 2.0 mM sodium sulfate solution: 0.026g
Show typed calculations to determine the mass of sodium sulfate necessary to prepare each of the three stock solutions in part A (These should be different values from the gram quantities listed in the ‘data to be used’). Clearly label each calculation and report the final answers to appropriate number of significant figures.
Using the actual mass of sodium sulfate given in the “data to be used” section, type the calculation to determine the actual molarity of the 5.0 g/L solution. Report the final answer to appropriate number of significant figures.
Develop a table that summarizes the calculated mass of sodium sulfate, the actual mass of sodium sulfate used listed in the ‘data to be used’, the molarity for all solutions from part A. Be sure that sodium sulfate concentrations reflect the actual molarities, not the target concentration listed in the lab manual.
