Question 4 and 5 only

For question 4 molarity for h2o2 from titration was found to be 0.4848 M/L convert this to g/dm^-3 please thx

a Mnog + 7 Pipette 25 cm of the original stock H2O2 solution (approximately "10 vol") into a 100cm volumetric flask and make up using distilled water. Label this as solution A. Pipette 25cm of this solution (A) into a conical flask, add 100 cm of water and 20 cm of H2SO4, (4 M, use and store in the fume-hood). Immediately titrate this solution with standard KMnO4 solution (0.1 M) to the first permanent colour change. Repeat titration to obtain agreeing titre values to within 0.1 cm>(x3) H2O 2 In your lab-book exception (1) Write out equations for the reactions involved (refer to first year manual). (2) Calculate the molarity of the hydrogen peroxide in Solution A. (3) Use the answer to (2) to calculate the volume strength of the hydrogen peroxide in the original stock solution. (4) Calculate the concentration of H2O2 in g dm in the original stock solution -3 (5) Why did you add the sulphuric acid before titrating with permanganate? React KMnO4 + M202 KMnO4 + M2 O 2 Mn 27 4 i of 2 (+1)(-1) oxolation E gale
