What is the integer value of the molarity of a CH3OH solution with a concentration of 1.225 M?

Baking soda (sodium bicarbonate, NaHCO₃) reacts with acids in foods to form carbonic acid (H₂CO₃), which in turn decomposes to water and carbon dioxide gas. In a cake batter, the CO₂(g) forms bubbles and causes the cake to rise. (b) The density of baking soda is 2.16 g/cm³. Calculate the concentration of lactic acid in one cup of sour milk (assuming the rule of thumb applies), in units of mol/L. (One cup = 236.6 mL = 48 teaspoons).
