How much can a cotton ball soak up?

A standard cotton ball can absorb approximately 15 to 20 times its weight in liquid, depending on factors like the density of the cotton and the type of liquid. On average, a cotton ball weighs around 0.5 to 1 gram, allowing it to soak up about 7.5 to 20 milliliters of liquid. Its high absorbency makes it useful for various applications, including medical and cosmetic uses.
