The calculations are getting to me in chemistry, every time i do one I haven't converted it correctly, or there was no need to convert or something...
does anyone have any calculation questions i can use to practice, practice, practice. I have done most past papers and I want new ones.. just working out concentrations and moles and all that..and even heat of combustion...
any help would be much appreciated
