Type here to search Consider the following balanced redox chemical equation to answer this question. 4 Mn²2+ + 5 As2O3 + 4 MnO4 + 9 H₂0 - 10 AsO4³- + 0.289 g of NaMnO4 (MM = 142.) were dissolved in enough water to produce 50.0 mL of solution. This solution was then placed in a buret. It required 40.58 mL of this solution to react with a 0.566 g sample of impure As2O3 that had been dissolved in hydrochloric acid. Given this informaion, calculate the mass (in g) of As2O3 (MM = 198) that were present in the impure sample. Report your answer to 3 significant figures.
