dilution blues :(

hey guys

i need to dilute some 8M hydrogen peroxide 50x for a titration. i figured i'd probs need a total of 100cm3 hydrogen peroxide solution for the experiment (i.e. 20cm3 per titration) but i'm having some issues with the practicality of the dilution

it's suggested we use a volumetric flask and a pipette in order to do it. so would i do something like add 2cm3 H2O2 using one of the squidgey pipette things to a 100cm3 volumetric flask, then fill it to the top using distilled water??

the figures seem a bit weird to me...what to you guys reckon? does it seem right?

thanks for the help!!!!!

Looks fine to me. What's weird about it?

Additionally, if you have a slightly larger volumetric, it won't hurt to make a little more in case you mess up a titration.
