It was decided to analyze a waste solution that contains an unknown concentration of mn2+ ions using colorimetry. a strong oxidizing agent was added to a 7.80 ml sample of the solution to convert the colorless manganese ions into purple permanganate ions. after the reaction is complete, the solution was diluted to 250.0 ml and analyzed in a colorimeter. the percent transmittance of the solution was determined to be 52.8%. also a calibration curve was prepared by using a series of solutions with known concentrations of permanganate and the equation for the best fit line was found. y =1920- x +0.026 what is the absorbance of the permanganate in the diluted absorbance = waste solution? what is the concentration of the permanganate in the diluted concentration of the permanganate = м waste solution? what is the concentration of the mn2+ ions in the original concentration of the mn2+ ions = м waste solution?

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
