Part b redox titrations are used to determine the amounts of oxidizing and reducing agents in solution. for example, a solution of hydrogen peroxide, h2o2, can be titrated against a solution of potassium permanganate, kmno4. the following equation represents the reaction: 2kmno4(aq)+h2o2(aq)+3h2so4(aq)→3o2( g)+2mnso4(aq)+k2so4(aq)+4h2o(l) a certain amount of hydrogen peroxide was dissolved in 100. ml of water and then titrated with 1.68 m kmno4. what mass of h2o2 was dissolved if the titration required 17.8 ml of the kmno4 solution? express your answer with the appropriate units. view available hint(s) mass of h2o2h 2 o 2 = previous answers incorrect; try again; 5 attempts remaining provide feedback incorrect. incorrect; try again; 5 attempts remaining. no additional feedback.

The zinc within a copper-plated penny dissolves in hydrochloric acid if the copper coating is filed down in several spots (so that the hydrochloric acid can reach the zinc). the reaction between the acid and the zinc 2h+(aq)+zn(s)→h2(g)+zn2+(aq) . when the zinc in a certain penny dissolves, the total volume of gas collected over water at 25 °c is 0.947 l at a total pressure of 743 mmhg . (vapor pressure of water is 23.78 mmhg at 25 °c .) what mass of hydrogen gas is collected? answer in appropriate significant figures
