A chloroform solution of caffeine (C8H10N4O2) contains concentration of 0.0868 m . compute mole fraction of caffeine(C8H10N4O2), the molarity of the solution, % w/w of caffeine(C8H10N4O2). If it is given that; The density of the solution = 1.523 g/mL. molar mass of caffeine (solute)= 194.2g/mol ;molar mass of chloroform, CHCl3, (solvent) = 119.4 g/mol
