chemistry revison

I'm doing GCSE Chemistry with Edexcel, and have my C3 exam coming up and I really struggle with equations such as Avogardro's law. It takes me a while to understand the method. Can anyone help me? Thanks

Well I do understand it, but it takes me a while to understand it, and I don't think I'll remember to convert cm3 into dm3 as i'll forget. Will i get the equations in the exam?

What equations? Do you mean like concentration = moles/volume? and number of moles = mass/Mr ?

well in my book it says volume of gas=mass of gas/Mr of gas x 24 and a triangle with volume=moles x 24....
