After throwing the ball in the pool for my dog ball sprung a leak and began to fill with water. How many milliliters of water can the ball absorb before it sinks?

To determine how many milliliters of water the ball can absorb before it sinks, you would need to know the ball's volume and density. If the ball's weight when filled with water exceeds the buoyant force, it will sink. Generally, if a ball is designed to float, it can absorb a small amount of water before becoming too heavy. A typical dog ball might hold anywhere from a few milliliters to around 50 milliliters, depending on its size and material.
