Hi.

Is there any way I could get some help on what the formula is that I would use to calculate mmol HCL / mg sample + possibly the work with it too?

Average Molairty of NaOH: 0.0984862M

Average Molarity of HCl: .402480M Thanks!

You measured the mass of 3 antacid tablets. What is the average mass of 1 antacid tablet? Mass (g) Please complete the following table. For each of your trials, enter the mass of crushed antacid tablet (g) dissolved in HCl, the volume of HCl(mL) used to dissolve the sample, the corresponding volume of NaOH(mL) required to reach the endpoint, and the calculated mmoles of HCl needed to neutralize 1mg of sample. Use the average molarity of your NaOH solution and the average molarity of your HCl solution in your calculations. x No, the value you entered for the equivalent millimoles HCl per milligram antacid sample is incorrect. Remember that mol/g=mmol/mg The difference between the millimoles of HCl used to dissolve the sample and the millimoles of NaOH required to titrate the residual acid, when divided by the antacid sample mass in milligrams, is the number you are seeking
