The density of sodium bicarbonate, commonly known as baking soda, is approximately 2.2 grams per cubic centimeter (g/cm³).
To put this into perspective, density is defined as mass per unit volume. In the case of sodium bicarbonate, this means that for every cubic centimeter of the substance, it has a mass of about 2.2 grams. This characteristic is important in various applications, including cooking, baking, and even in medical uses, where precise measurements are crucial. Understanding the density can help in determining how it interacts with other substances and in calculating the quantities needed for specific recipes or chemical reactions.
