Calculate molarity from concentration
Weba. Using the molarity and volume of titrant added, determine the moles of titrant added to your solution at the second endpoint of the titration. Volume = 23.6 mL b. Using molecular equation, calculate the moles of sodium carbonate titrated c. Based on (b), calculate the concentration of sodium carbonate in units of ppm or mg / L. This is a ... WebFirst, calculate the number of moles of strong base required to reach the equivalence point of the titration. Then, using the mole ratio from the balanced neutralization equation, convert from moles of strong base to moles of acid. Finally, divide the number of moles of acid by the given volume of the acid solution to find the concentration.
