At 25 degrees Celsius (77 Fahrenheit) and standard pressure (101.3 kPa) one pound of helium would fill 2768 Liters (731) Gallons It depends on how big you want to fill the balloons, the pressure of the balloons the temperature and a range of other things.
The average helium balloon can lift about 14-16 grams, or approximately 0.03-0.04 pounds. To lift 30 pounds, you would need around 750-1000 average helium balloons.
The number of balloons needed to lift a child would depend on the weight of the child and the size of the balloons. On average, it may take around 80-100 helium-filled balloons to lift a small child off the ground. It's important to consider safety measures and proper balloon handling if attempting such a stunt.
assuming that temperature is constant and that we're talking about regular party balloons (a "regular" 2-gram party balloon can hold ~ 16 grams of gas), you would need 6,156 baloons to hold your weight in equilibrium. you would need an amount greater than this to actually lift you (the more extra balloons, the faster the lift), and this is not accounting for the weight of the string. extrapolated from: http://malaysia.answers.yahoo.com/question/index?qid=1005123102737
Well, honey, it's not the number of balloons that'll kill you, it's how you use them. Inhaling helium straight from a tank can lead to oxygen deprivation and potentially cause you to pass out or suffocate. So, let's stick to using balloons for parties and leave the risky business to the professionals, okay?
It would take roughly 67 weather balloons to lift a 190 lb person. Each weather balloon can lift around 3 lbs of weight, so dividing the person's weight by the lifting capacity of one balloon gives the approximate number needed.

10000000 helium balloons
The average helium balloon can lift about 14-16 grams, or approximately 0.03-0.04 pounds. To lift 30 pounds, you would need around 750-1000 average helium balloons.
it took 53 12" helium balloons to lift a pound, you have to add the weight of the string and balloons
The number of helium balloons needed to lift a person will depend on the person's weight. On average, it takes about 3-5 large helium balloons to lift 1 pound. For example, to lift a 150-pound person, you would need roughly 450-750 balloons. It is important to consider factors like air currents and ceiling height when attempting to lift objects with helium balloons indoors.
depends on how large the balloon is! ;D
It would take approximately 480 helium balloons to lift a 20-pound frozen turkey. Helium can lift about 0.04 lbs per balloon, so 20 lbs divided by 0.04 lbs per balloon equals 500 balloons.
To lift about 110 pounds it could take any where from 100 to 150 balloons to lift a person, a lawn chair, food, and many gallons of water. A man by the name of Kent Couch from Oregon demestrated this for us by flying from his home all the way to Idaho. I would'NT try this unless you have a parachute of some kind of device to help you have a better landing. The Balloons could be about the average party balloons (large ones) that are about 11in in diameter. Now remember this is very dangerous and could even be lethal.I hope this helped you.Thanks for looking--Tiana5701

Assuming one party balloon can lift about 14 grams, it would take approximately 129 party balloons to lift 64 pounds. However, this is a rough estimate as variables such as balloon size, air temperature, and altitude can affect the lifting capacity.
25 Balloons (Approx.)(I might be wrong as I am not sure)
