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.

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.
What is the mass of 18.8 moles of helium atoms?
1 mole of helium weighs 4.0026 g So. 18.8 of helium will weigh 75.25 g
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
Calculate the gram atom in 22.4 liters of helium?
22.4 litres of helium will weigh 4 grams and will have 6.023 x 1023 atoms (1 mole)
Name something that weighs 1 gram?
1 ml of water, one mole of hydrogen or 1/4 moles of helium.

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!
Is helium lighter than air?
Yes, a mole of hydrogen weighs 1 g, a mole of helium weighs 4 g. Still lighter than air, as a mole of air weighs about 30 g.
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.
How many liters is one mole of helium?
22.4litres
How many moles in 6.45 x 10 tenth grams of helium?
4 g of Helium will have 1 mole. So, 6.45 x 1010 g of Helium will have 1.61 x 1010 mole.
Which has the largest mass A 3 mol of magnesium B 1 mol of sucrose c12h22o11 C 10 mol of helium?
Since magnesium and helium do not form elemental molecules, a mole of these elements is the same as a gram atomic mass, which is 24.305 for magnesium and 4.00260 for helium. The gram molecular mass for sucrose is 342.30. Therefore, the mass of: A. 3 moles of magnesium is 72.915 grams; B 1 mole of sucrose (C12H22O11) is 342.30 grams; and C. 10 moles of helium is 40.0260 grams. The largest of these is obviously the single mole of sucrose.
