How many molecules in baking powder?

Baking powder typically contains several components, including an acid (like cream of tartar), a base (usually sodium bicarbonate), and a starch to prevent clumping. When mixed with liquid, these ingredients react to produce carbon dioxide gas, which helps baked goods rise. The exact number of molecules in baking powder would depend on the specific formulation and quantity used, but in general, a single teaspoon of baking powder contains billions of individual molecules.
