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.

WebThe relationship between molarity, moles and volume are shown below. where M = molarity (M or mol/L), n = number of moles (mol) and v = volume (L). Step 1: Determine which formula to use. We were given the number of moles of the substance and the volume of solvent used. We do not know the concentration in molarity. Webto determine the amount of solute in some other volume if we know the molarity; let x2= the volume of solute; y1= the number of moles in an initial volume x1. The ratio y1/x1is often called the molarity. We can then use the same equation we discussed in We might instead simplify it to (1) mol = V*M
