    Hi,



    we recently did this experiment on the stoicheiometry a comlex. I have the results and everything but I'm stuck on how to start the calculations and what calculations we should use as our teacher is away at the moment and we've never had practice with lab reports before... Can someone please help me out here?

    these are the results:
