Ok, this would be a problem of essentially displacement as the lift is caused by displacing "air".
Ok, so one needs the densities of air and helium at some given temperature and pressure... "STP" is common, although one really would need to do it at the ambient temperature... or to do the final conversion using the simple formula PV=nRT.
According to answers.Yahoo.com, the densities of air and helium at STP are:
Density of helium = 0.0001785 g/cm³
Density of air = 0.001293 g/cm³,
Ok, so your questions is how many cm³ of helium are needed to lift 1 gm.... let's try to make an equation.
So, if we displace X cm³ of air with Helium we have:
(X cm³)*(Density of Air g/cm³) - (X cm³)*(Density of Helium g/cm³) = (mass displaced in grams).
Set the amount of mass being displaced to 1 gram, and putting in the densities we have:
(X cm³)*(0.001293 g/cm³) - (X cm³)*(0.0001785 g/cm³) = 1 g
(X cm³)*(0.001293 g/cm³ - 0.0001785 g/cm³) = 1 g
(X cm³) = 1g/(0.001293 g/cm³ - 0.0001785 g/cm³)
(X cm³) = 897 cm³
You had asked in liters... with 1000 cm³/liter, the answer would be:
0.897 liters of helium would displace 1 gram of oxygen without taking into account the weight of the container, or any pressure imposed by inflating container such as a rubber balloon.

One mole of any gas at standard temperature and pressure (STP) occupies 22.4 liters. Therefore, one mole of helium would also occupy 22.4 liters at STP.
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.
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.
10000000 helium balloons
The number of moles of helium is 0,32.

depends how big the helium balloon is and how many
1 mole occupies 22.414 liters So, 1.84 moles will occupy 41.242 liters
1 mole = 22.414 liters So, 3.5 mole = 78.45 liters
About 0,85
To inflate a balloon to a desired size, we need to know the volume and required lift. Typically a 9-inch helium-filled balloon can lift about 8g of weight. If you want to increase the lift, you can add more helium.
One mole of any gas at standard temperature and pressure (STP) occupies 22.4 liters. Therefore, one mole of helium would also occupy 22.4 liters at STP.

well a gram is its own type of measurement as is liters or in your case inches>>> now u can measure the inches on an object tht ways a gram but not the actual gram itself
depends on how large the balloon is! ;D
