the mole chap is goood there....
if u want i can gve u all the formulas tht u have to learn by heart... if u r guud at maths it wudnt be a prob

I'm preparing my moles without formulas. Ratio methods work best.

 

[sksuriza]

sometimes they r looking for formula in qs so b on the safe side..

i have the prescot book and i do have the formulas
i get confused in analysing the question

a good trick
i usually do this..
1st write down all the information thy have given shortly..
like
mr=18
vol at rtp=24dm3
mass= 35g
vol =?

now look 4 the formula whch have all these ie combine the formula
n=mass/Mr
n=vol/mol vol

u get
mass/Mr=Vol/mol vol

this makes work quite easy
