By definition, one mole would be the same as the Atomic Mass. You take the number of moles and multiply it by the atomic mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will be the atomic mass. Helium's atomic mass is 4.003 grams.

Calculate the gram atom in 22.4 liters of helium?
To calculate the number of gram atoms in 22.4 liters of helium, we first need to convert the volume to moles using the ideal gas law. Since helium is a monoatomic gas, 1 mole of helium is equivalent to 4 grams (its molar mass). Therefore, the number of gram atoms in 22.4 liters of helium would be 22.4 liters * (1 mole / 22.4 liters) * (4 grams / 1 mole) = 4 grams.
What is the mass of 18.8 moles of helium (He) atoms?
1 mole of helium weighs 4.0026 g So. 18.8 of helium will weigh 75.25 g
How many moles are there in 0.12g of helium?
4 g or helium is 1 mole. So, 0.12 g of helium is 0.03 mole
How many grams of barium chromate are there in one mole?
The molecular weight of Barium Chromate (BaCrO4) is 253.37.Therefore, one Gram Mole weighs 253.37 grams.When handling this chemical REMEMBER, it is Poisonous!
Which sample contains the same number of atoms as a gram atomic mass of he?
A gram atomic mass of helium (He) contains the same number of atoms as 1 mole of helium. Since 1 mole of any substance contains approximately 6.022 x 10^23 atoms, a sample of helium with a gram atomic mass would contain that same number of atoms.
Name something that weighs 1 gram?
1 ml of water, one mole of hydrogen or 1/4 moles of helium.
What is the molar mass of a molecule that weighs 1 dalton per mole?
The molar mass of a molecule that weighs 1 dalton per mole is 1 gram per mole.

How many pounds per pound-mole is equivalent to 1 gram per gram-mole?
To convert 1 gram per gram-mole to pounds per pound-mole, you would multiply by 0.00220462.
How many moles are there in 0.12g of helium?
4 g or helium is 1 mole. So, 0.12 g of helium is 0.03 mole
How many grams of barium chromate are there in one mole?
The molecular weight of Barium Chromate (BaCrO4) is 253.37.Therefore, one Gram Mole weighs 253.37 grams.When handling this chemical REMEMBER, it is Poisonous!

Does 1 mole of hydrogen atoms equals 1 mole of helium atoms?
No, 1 mole of hydrogen atoms does not equal 1 mole of helium atoms. One mole of any element contains Avogadro's number of atoms (6.022 x 10^23), so 1 mole of hydrogen atoms would have that many hydrogen atoms, while 1 mole of helium atoms would have that many helium atoms.
What is Mass of a gram mole of aluminum?
1 gram mole of Aluminium is about 27g.
Is helium lighter than air?
Yes, helium is lighter than air. Helium is a lighter-than-air gas that has a lower density compared to the gases that make up our atmosphere, such as nitrogen and oxygen. This is why helium-filled balloons float in the air.
What is the total mass contained in 2.00 moles of helium?
1 mole of helium weighs 4.0026 g. So 2 mole will weigh 8.0056 g.
