The molarity of this solution may be determined by applying the following formula:
Density x w/w% x 1000 / Mw. Thus, 1.209 g/mL x 90% x 1000/ 90.08 g/mol = 12.08 M.

In animals, lactic acid is a metabolic compound produced by proliferating cells and during anaerobic conditions such as strenuous exercise. Lactic acid can be oxidized back to pyruvate or converted to glucose via gluconeogenesis. Lactic acid is preferentially metabolized by neurons in several mammal species and during early brain development.
Other Notes
A concentrated solution of lactic acid is typically a mixture of lactic acid lactate and lactic acid. The concentration of this solution is approximately 90% (w/w).

Hello For Lactic Acid (L6661-100ML), it says that its 90% concentrated (w/w). I'm trying to determine the molarity of the stock solution and am not sure how to proceed with this. Is this solution 0.9M because of the 90%? Any help is appreciated-Thanks!
