can someone plz help in stochiometry?

Question

i want to score the highest marks can someone plz provide me some sites where i can easily understand the topic n i need some shortcuts 4 easy calculation...plz help

Answer 1

www.wikipedia.com

thats all i know of and internet is not the perfect place to practice some math

heres a shortcut of mine;

try manipulating formulas
connect them eg. u can make the mole for mula and ideal gas formula as one by substitution. i'll leave that up to you to figure how.



and it better for u to practice from your book do as many as u can and stoichiometry is not as hard u just need to get a grasp of it .

as they say practice makes perfect

Answer 2

simplest way to understand stochimetryic questions is to look at the units of each things

For example concentration:
mol/dm3 so to find it you divide no. of moles by the volume you dissolve it in.

or g/dm3 similarly you divide no. of grams by the volume you dissolve it in

and if you know the concentration and volume of soulution and want to find the no. of moles you simply multiply concentration by volume to get no. of moles
