I need help setting up the last two parts of this problem. I do not want the answer, just to understand how to set it up and why.
Sodium hydrogen carbonate, NaHCO3 is a base used in several commercial antacids. The overall reaction with HCl is: NaHCO3(aq) + HCl(aq) â NaCl (aq) + H20 (l) + CO2 (g) 1. A tablet, which had a mass of 1.213 g, was pulverized and 0.613 g were dissolved in 25.00 mL of 0.220 M HCl. The titration of this solution with 0.1615 M NaOH required 26.30 mL to reach the phenolphthalein end.point. Determine the moles of HCl that were added to the sample analyze I found this answer to be.00550 mol 2. For the previous problem, determine the moles of HCl that reacted with the NaOH. I found this answer to be 0.00425 mol These last two are where I am stuck and don't know how to set up the problem. I don't want the answer, I just want help understanding how to set it up. 3. Determine the grams of NaHCO3 in the sample analyzed. 4. Determine the mass of NaHCO3 in the tablet.
