i did try many time to open all those links but NO possible...!
but anyway, i went to another sources then found out that I thought I understood it in the class but still got confused after reading all those articles, my brain is fried on this mole thinging... the more i read the more i fried... esp. the concept map is on its way..
what I think I understood in the class was that to calculate how many molecules, just take the molecule weight of an element then multiply by Avogadro's number, then u get the mass in grams...
mmm, I'm feeling a little lost in transition. I'm going to walk through everyone else's blog now!
