Dunno if am supposed to ask this on this site but no other option.

We have been taught mole concept in chem...didnt...asked teacher...but she new and not good...not understood.

It would be a great help if anyone of u explain it to me.quickly cause exams on the way

i know a mole is 6X10^23 molecules (not sure that's how you write molecule...) it is used when you want to talk about a bunch of molecules, and not simply one or two, i guess you know about chemical equasions, like O+2H =(arrow) H2O, the idea is that it is unlikely that if you take only 2 Hs and 1 O to make water becasue they wouldn't even touch each other, so when you see this equation you think about 1mol of O and 2mol of H that untimately gives you 1mol of H2O. it's not very important, becasue you won't be dealing with it so much, the way schools teach chemistry is very slow and annoying, lots of stupid politicaly correct stuff, my teacher really dissapoints me.

thanks
