Determine the mass of CaCO3 in your TUMS tablet?

The weight of the tablet was 0.013g
Concentration of HCl was 0.1494 M
Volume of HCl was 95 mL
Concentration of NaOH was 0.1422 M
The average amount it took to titrate was 2.13 mL

I have determined that moles of HCl neutralized was 0.014039514 and when I divide by 2 and multiply by the molar mass of CaCO3 I get 0.702607478 which is way more than the weight of my TUMS

I can't figure out what I did wrong

  1. You may want to double check the weight of your tablet as your current one is extremely light.
