i have done everything i can think of to get the answer to this but i cant seem to get it right! i must be doing something wrong! Any help with be greatly appreciated! Question 6. Calculate the concentration of hydrogen peroxide in the 10 mL aliquot, taken from the reaction if the titration with 0.0168 M permanganate solution requires 24.8 mL to reach the end-point

um.... i still dont understand.. could u explain it a little more? thanx

hi, if anyone could help me remember how to do these questions it would be greatly appreciated i just have a memory block and think i am forgetting something when trying to get the answer to these. a) How many moles of hydrogen peroxide react with each mole of permanganate in the titrationmoles of MnO4- per mole of H2O2 b) Calculate the concentration of hydrogen peroxide in the 10 mL aliquot, taken from the reaction if the titration with 0.0176 M permanganate solution requires 32.8 mL to reach the end-point c) If the concentration of hydrogen peroxide in the 10 mL aliquot is 0.0568, calculate ln([H2O2]) you don't have to answer them a little nudge in the right direction would be good though cause i used to be able to do them!

Help with this question would be greatly appreciated, i just cant seem to get the answer, estimate the percentage of empty space in gaseous argon, given that the radis of an argon aton is 192pm (1.92x10-10m)

you multiply the concentration by the whole mass. then you devide the mass of 3CL by the whole mass, to get only anions.

thankyou everyone it was a great help

i am trying to work out these questions but i cant seem to get the right answer. any help we be appreciated. question one: Calculate the chemical amount of anions in 79.0 mL of a 0.4564 M solution of cobalt(III) chloride question 2: Calculate the concentration of anions if 100.0 mL of a 0.3530 M solution of iron(III) sulfate is diluted with water to the mark in a 500.0 mL volumetric flask

Calculate the concentration of anions in a solution prepared by dissolving 0.605 g of cobalt(III) chloride in sufficient water to produce 350.0 mL of solution. Anyones help would be greatly appreciated
