How many helium balloons would you need to fly in the house?
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.
How much helium is in a balloon that contains 0.54 grams of helium gas?
To calculate the amount of helium in the balloon, we need to convert the mass of helium gas to moles using the molar mass of helium. The molar mass of helium is 4 g/mol. So, 0.54 grams of helium is equal to 0.54/4 = 0.135 moles of helium. Finally, we can use Avogadro's principle to convert moles to the number of helium atoms present in the balloon.
Helium atoms only need how many valence electrons to have a filled outermost energy level?
Helium atoms only need 2 valence electrons to have a filled outermost energy level because helium is in the first period of the periodic table and its outermost energy level can only hold a maximum of 2 electrons.
Do you need helium to make a balloon float?
Yes.
How much helium is in a balloon that contains 0.54 grams of gas?
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
How much helium would it take to lift 2000lbs?
to lift 1 kg or 2 pounds you need 0.16 kg of helium so for 2000 pounds you need 160 kg of helium or 320 pounds at 1 atmosphere

How much do you need to open a balloon shop?
a tank of helium and alot of those balloon thingy's
In To Kill a Mockingbird who is in need of a friend?
One example of a person who is in need of a friend is Boo Radley.
How much helium is needed to lift 400 pounds?
To lift 400 pounds, you would need approximately 74.3 cubic feet of helium. Helium is lighter than air, so it provides lift when contained in a balloon.
Why do starts need helium?
stars* and they don't need helium they make helium from hydrogen using nuclear fusion omg im 13 and i know this
How much helium is needed to lift 1 lb?
You would need approximately 65 cubic feet of helium to lift 1 pound. Helium provides lift because it is lighter than the surrounding air, creating buoyancy.
Why does your body need helium?
Your body does not need helium. Helium is an inert gas, and it is not found as a "building block" of any organic material, or any other materials for that matter.
What is helium ions?
Helium ions can be synthesized by removing electrons from a helium atom and it would need a tremendous energy.
Can a sound wave kill a person?
A sound wave can kill a person because let's say its too loud yes it can because the pressure between the person and the sound wave is too much and is it explodes you ears that make your brain go out of function
How much space Does a person need?
depends on the person each personis much diffrent in needs. give them as much as they ask for..
