Is the total mass after fusion greater or less than before fusion?
The total mass is less after a fusion reaction. Some of the mass is converted into energy and given off due to the nuclear fusion reaction. For example. 2 atoms of hydrogen are fused to become 1 atom of helium. However, the helium atom will have less mass than the combined mass of the 2 original hydrogen atoms. The excess mass is lost via the energy given off from the nuclear fusion reaction.
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
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.
An atom of helium has a mass about four times greater than that of an atom of hydrogen Which choice makes the correct comparison of the relative numbers of helium and hydrogen atoms in equal masses o?
the number of helium and hydrogen atoms is the same
How many Helium-atoms and Carbon-atoms do you have if you have He-atoms with mass of 40amu and C-atoms with mass of 120amu?
Mass of 1 Helium atom is 4 amu and mass of 1 Carbon atom is 12 amu. So there are 10 helium atoms and 10 carbon atoms
What is the mass of 5 moles of he atoms?
5 moles of helium He atoms is equivalent to 20,013 g.
Is the The mass of 4 individual hydrogen atoms is more than the mass of 1 helium?
Yes.

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
Which element is the smallest?
If you are talking about individual atoms, it is hydrogen by mass or helium by radius.
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 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.

the number of helium and hydrogen atoms is the same
Which has greater number of atoms a gram of helium or a gram of neon?
Neon is larger because it has more protons, electrons, and neutrons. Look at the element's Atomic Mass for an idea of its size.
