What is the percentages by mass of each element constituting the caffeine?
The chemical formula of caffeine is C8H10N4O2 and the molecular mass is 194,19. - Carbon - 49,464 % - Nitrogen - 28,860 % - Oxygen - 16,483 % - Hydrogen - 5,193 %
Define mole of mass over volume?
Yes the number of moles = the number of grams in a given sample / the molecular mass of the substance. Ex. to convert 50 grams of nitrogen to # of moles of nitrogen, you divide 50g by 14.01g (the molecular mass) and you have 3.57 mol Nitrogen
