    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 ?
