4 grams.
Approximately, mass (in grams) of 1 mole of any chemical element is just the Atomic Mass of this element (4 - for He, 12 - for C, and so on). It follows from the definition of one mole - number of atoms in 12 g of C.

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
What is the number of atoms in 1.5 moles of helium if you calculate it?
1 mole of helium has 6.023 x 1023 atoms. So, 1.5 mole of helium will have 9.035 x 1023 atoms.
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.
What has a greater mass 2 atoms of lead or 5.1 X 10-23 mole of helium?
The weight is greater for 2 atoms of lead.

Is a 16.00-g sample of oxygen atoms contains the same number of particles as a 4.003-g sample of He atoms?
Yes. 16.00g of oxygen is its molar mass, which is the mass of one mole of oxygen. 4.003g is the molar mass of helium, which is also the mass of one mole of helium. One mole of anything is 6.022 x 1023. One mole of oxygen atoms is 6.022 x 1023 atoms of oxygen and one mole of helium atoms is 6.022 x 1023 atoms of helium.

What is the mass in grams of 3.40x10 22 atoms He?
3.40 X 1022 atoms helium (1 mole He/6.022 X 1023)(4.003 grams/1 mole He) = 0.226 grams ===========
What has a greater mass 2 atoms of lead or 5.1 X 10-23 mole of helium?
The weight is greater for 2 atoms of lead.
What is the mass of one mole atoms?
The mass depends on the element whose atoms are concerned. For eg, 1 mol Helium atoms have mass 4 g 1 mol Neon atoms have mass 20 g.
Explain why a mole of iron atoms has more mass than a mole of helium atoms when there are the same number of atoms in a mole of each element?
A mole of iron has more mass than a mole of helium, even though they contain the same number of atoms, because 1 atom of iron has a greater mass than 1 atom of helium. It is similar to why 1 dozen bricks has a greater mass than 1 dozen roses. There are 12 items in each case, but 1 brick has a greater mass than 1 rose.
What is the mass of 2.50 mol of Helium?
Helium molecule is mono atomic. 1 mole = 6.023 x 1023 atoms of helium So, 2.5 moles = 2.5 x 6.023 x 1023 atoms of helium or 15.058 x 1023 atoms of helium
What is the mass of six helium atoms?
32 g
How much atoms does helium have?
Atomic Mass of helium is 4.002602
