An average table tennis ball has a diameter of 3.812cm. And a mass of 2.676 grams. Assuming that air buoyancy is included, what will be the density of air (in kg/m^3) needed to make the table tennis ball is a depth of h = 7.032 mm., in a liquid with specific gravity of 1.007? Neglect any temperature change that could after the density of air. Assume the ball to be a sphere.
