Question
What is the volume in milliliters of 0.1069 M Cr2O72- required to react with 252.4 mL of 0.08013 M Cl- according to the reaction below?
6 Cl-(aq) + Cr2O72-(aq) + 14 H+(aq) ® 3 Cl2(g) + 2 Cr3+(aq) + 7 H2O(l)
6 Cl-(aq) + Cr2O72-(aq) + 14 H+(aq) ® 3 Cl2(g) + 2 Cr3+(aq) + 7 H2O(l)

mols Cl^- = M x L = ?
Using the coefficients in the balanced equation, convert mols Cl^- to mols Cr2O7^2- and that is mols Cl^- x 1/6 = ?
The M Cr2O7^2- = mols/L. You know M and mols, solve for L and convert to mL.
