A sphere with 3-ft diameter has about 0.4 cubic metre of volume.
How much a helium balloon carries depends on the size of the balloon.
Soccer balls do not contain helium. if they did, they would float like a balloon! Actually, that's not true. A soccer ball would NOT float like a balloon--they weigh too much. It would, however, increase the distance ever so slightly over that of a regular air filled soccer ball. Eventually over time, the helium would dissipate, much like a helium balloon that slowly falls to the ground.
The weight of the helium gas inside the balloon can be calculated using its molar mass, the Ideal Gas Law, and the given volume. Assuming standard conditions, helium gas has a molar mass of 4 grams per mole. Thus, a 22.4 liter balloon filled with helium gas would weigh approximately 32 grams.
A standard 11-inch helium balloon can lift approximately 14 grams or 0.5 ounces. The lifting capacity of a helium balloon can vary depending on factors such as balloon size, helium volume, and weight of the attached object.
depends how big the helium balloon is and how many

a tank of helium and alot of those balloon thingy's

because helium weighs 4u and air (80% nitrogen) weighs about 14u. because helium has less mass, it has less gravity and rises. it has also to be a gas as a substance in a gas form has a much lower density as a liquid or solid form. earlier they used hydrogen (1u), but that is highly explosive. (u is relative mass for atoms)
* Calculate the volume of the ballon * Calculate the weight of the helium: G= V x 0,1786 (the helium density in g/L) * Add the weight of the balloon material (rubber, plastic, etc.)
0.54 grams 1 mol = mass / Mr = mass / 4 (Helium's atomic weight is 4, it is a monoatomic gas) 1 mol = 0.54 / 4 = 0.00135 # of molecules of helium in the balloon = 0.00135 * 6.02 * 10^23
I would say that depends on the size of the balloon, the gas used to fill the balloon and the atmospheric pressure. Based on these parameters, a balloon may take anywhere from a few minutes to few hours to deflate.
Carbon dioxide will keep a balloon inflated longer than helium will, because its molecules are much larger and therefore less able to escape through the material of which the balloon is made.On the other hand, helium is much lighter so will give a balloon greater lift while it lasts.
