Milagros Posted November 20, 2019 Report Share Posted November 20, 2019 My internal chemical research is to evaluate different concentrations of lactic acid in calcium carbonate to determine its demineralizing effect, however I have only determined to measure the molar mass before and after and now I have no idea what dependent variable to include should I modify anything ? Is the subject simple? What should I do to improve it? Reply Link to post Share on other sites More sharing options...
