What is the mass of a dry sponge?

The mass of a dry sponge can vary widely depending on its size, density, and material composition. Typically, a small, standard kitchen sponge weighs around 30 to 50 grams when dry. Larger sponges, like those used for bathing or cleaning, can weigh significantly more. To determine the exact mass, it's best to weigh the specific sponge in question.
