We all have suffered at the hands of the chapter in Chemistry called Moles . Learning all those formulas at once is cumbersome and most of the time we have no idea which one is to be used .

Here are some notes on O level Moles (Prepared by Sir Saad Hameed). I had these in written form , but luckily came across this on an engineering site a few days back . In these notes a generalized technique is shown that will make moles a lot easier . It's easy to understand and apply. It's based on the ratio method . Try it out . If you don't understand anything let me know , and I'll explain it.
