Calculate the molar concentration of the hydrochloric acid solution if its titer is 0.03798 ml.

Given:
T (HCl) = 0.03798 g / ml

To find:
Cm (HCl) -?

Decision:
1) m (HCl) = n * M;
2) m (HCl) = T * V p-pa = n * M;
3) n (HCl) = T * V p-pa / M;
4) Cm (HCl) = n / V solution = (T * V solution) / (V solution * M) = T / M = 0.03798 / 36.6 = 0.001038 mol / ml = 1.038 M.

Answer: The molar concentration of HCl is 5.76 M.
