Determine the molar mass of an unknown monoprotic acid to two decimal places if 20.01 ml of a 0.098 m naoh solution were used to titrate 0.215 g of the unknown acid

By using the following formula we can calculate the volume;

C₁V₁ = C₂V₂

C₁ = concentration of starting solution = 0.098m

V₁ = volume of starting solution that is needed for titration = 20.01ml

C₂ = Desired concentration of final solution = ?

V₂ = desired volume of final solution = 0.215g = 0.215ml

Now putting the values in the formula;

0.098 x 20.01 = C₂ x 0.215

C₂ = 0.215 / 1.96098 = 0.109m = 0.11m

Thus, the answer is 0.11m.
