Ron makes soap balls and sells them at his local farmers' market. First, he uses a large cylindrical pot to mix and melt the ingredients. The pot has a diameter of 10 inches, and he fills it to a height of 10 inches. When everything is melted, he pours the liquid soap into small spherical soap molds that each have a radius of 1.5 inches. What is the maximum number of soap molds that Ron can fill completely using his soap mixture?
