Weight of graphene obtained w.r.t. weight of graphite used for the synthesis !

Tamoghna Bhattacharyya

You can simply measure it by Raman spectroscopy. If you can compare the ratio of defect to tangential band intensity in comparison with a pristine one(with fixed weight) then the purity level can indirectly measure the amount of synthesized graphene.
