What is the atomic weight of Helium atom?
Helium atom has 2 protons and 2 neutrons (that accounts for its atomic weight). The atomic weight of helium is 4.00260
What is the chemical mass for helium?
The atomic weight of helium is 4,002602(2).
How much would helium in the tires affect the weight of a semi trailer?
Using helium in tires would have a minimal impact on the weight of a semi-trailer. Helium is much lighter than air, but the amount of helium in the tires is very small compared to the overall weight of the trailer, so the difference in weight would be insignificant.
How do you convert 26.7kg of helium into moles of helium?
To convert grams to moles, divide the given mass by the molar mass of helium. The molar mass of helium is approximately 4g/mol. Therefore, 26.7kg of helium is equal to 26,700g, which would be 6,675 moles of helium.
How do you weight a balloon with hellium?
To weight a helium balloon, you can attach small weights to it until it stays grounded. By adding enough weight to counteract the lifting force of the helium, you can measure the weight of the balloon.
What is the weight of helium?
The weight of helium is very light, as it is one of the lightest elements on the periodic table. Helium has a very low density and weight compared to other elements.
What is the atomic weight of Helium atom?
Helium atom has 2 protons and 2 neutrons (that accounts for its atomic weight). The atomic weight of helium is 4.00260
What is atomic weight of helium?
4.002602 g/mol
What is the chemical mass for helium?
The atomic weight of helium is 4,002602(2).
Is a tank of helium lighter than a empty tank?
No, helium has weight, but it rises when its in an expandable container such as a balloon because it is lighter than the nitrogen rich atmosphere but inside of a rigid container the helium can only add weight. (see the mythbuster's episode about the helium football)
Why does helium have weight?
Helium has weight because it has mass and is subject to gravity. Despite being much lighter than other elements, helium still has mass and therefore experiences a gravitational force that gives it weight.

How many amu's does helium have?
Helium has a standard atomic weight of 4.0026 atomic mass units (amu).
What elements do helium make up?
The only element helium makes up is helium. Atomic number: 2 Atomic weight 4.00260 u (avg)
How much does helium weigh?
The density of helium is approx. 0,9 g/L.
