Yes, it does. But the weight added by gas (if that is what is being used to inflate it) does not change the weight of an average ball very darn much. You'd have to have a really sensitive scale to actually find the weight of the air in the ball. In fact, someone working in the lab wouldn't weigh the thing. They'd use the size of the ball to find its volume and then look at the pressure and temperature of the gas in the ball and make a calculation to determine the weight of gas. It'd be a loooot faster and probably as accurate - if not more so.

Mass and Weight The gravitational force Earth exerts on an object is the weight of the object. Because weight is a force, it is measured in newtons. Weight is not the same as mass. Mass is the amount of matter an object contains, and is measured in kilograms. Even if the mass of an object doesn't change, its weight will change if its distance from Earth changes.
