yes, what do you need to know about?

[Ice_Phoenix87]

lol the whole thing its alittle confusing, did anyone else have this problem?

[budullewraagh]

gah i dont want to teach you everything...search online. here's something you should know: 1 mole=6.02*10^23 molecules=grams*molecular mass

[ans]

Know the forumulae:

 

mr = mass/mole (for solids)

conc. = mol/dm^3 (for aq solutions)

mol = vol/24dm^3. (gases)

 

 

Type out an example question and it will make someone can help explain easier.
