To find the number of helium atoms in a helium blimp, you would first need to convert the mass of helium (431 kg) to moles using the molar mass of helium. Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to calculate the number of helium atoms.
To find the number of helium atoms, we need to convert the mass of helium to moles and then use Avogadro's number to convert moles to atoms. The molar mass of helium is 4 g/mol. First, convert 590 kg to grams (590,000 g). Then, divide by the molar mass of helium to find moles, and finally multiply by Avogadro's number (6.022 x 10^23 atoms/mol) to get the number of atoms.

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.
1 mole of helium weighs 4.0026 g So. 18.8 of helium will weigh 75.25 g
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
10g of helium has fewer atoms. This is because the atomic mass of helium is much higher than that of hydrogen, so the same mass of helium contains fewer atoms than the same mass of hydrogen.
Nitrogen is the heavier gas (mass of 28) compared to helium (mass of 4).

To find the mass of 3.40x10^22 helium atoms, you need to know the molar mass of helium, which is 4.0026 g/mol. So, the mass of 3.40x10^22 helium atoms would be 3.40x10^22 atoms * (4.0026 g/mol/6.022x10^23 atoms/mol) ≈ 2.27 grams.

5 moles of helium He atoms is equivalent to 20,013 g.
Yes.
When hydrogen atoms fuse into helium atoms, a small amount of mass from the hydrogen is converted into a large amount of energy in accordance with Einstein's equation E=mc^2. This energy release results from the difference in mass between the initial hydrogen atoms and the resulting helium atoms.
