About
Baking soda is a fine mineral powder that packs tightly, weighing about 7.5 ounces (213 grams) per cup.
Baking soda has a bulk density of about 56 pounds per cubic foot (0.9 grams per milliliter). Because its fine crystal grains pack together closely, it takes up much less space by weight than aerated powders like flour. A standard one-pound (454-gram) grocery box holds just over two cups of powder. In recipes, this density means even a small spoonful adds a significant amount of weight.
From Wikipedia
Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate), commonly known as baking soda or bicarbonate of soda, or saleratus, is a chemical compound with the chemical formula NaHCO3. It is a salt composed of a sodium cation (Na+) and a bicarbonate anion (HCO3−).
