hi all, hope you're all having a nice easter holiday! im not ha, doing chemistry coursework.
anyway! I'm quite stuck on how to work out the concentration of a solution that I've diluted.
the substance i'm using is potassium peroxodisulphate of concentration 0.040moldm^-3.
the concentration of 25cm^3 potassium peroxodisulfate with no water would be 0.040moldm^-3.
but what if I diluted it, say 23cm^3 of p.p with 2cm^3 of water, how would I work out the concentration?
thanks for your help!
