There are two different isotopes of bromine atoms. Under normal conditions, elemental bromine consists of Br2 molecules, and the

mass of a Br2 molecule is the sum of the masses of the two atoms in the molecule. The mass spectrum of Br2 consists of three peaks:
Mass (amu) Relative Size
157.836 0.2569
159.834 0.4999
161.832 0.2431
(a) What is the origin of each peak (of what isotopes does each consist)?
(b) What is the mass of each isotope?
(c) Determine the average molecular mass of a Br2 molecule.
(d) Determine the average atomic mass of a bromine atom.
(e) Calculate the abundances of the two isotopes.

What happened to the molecule when the electron was promoted to the antibonding orbital?.
____ [38]

the bond will break

The bond will dissolve (break) if the electron absorbs a photon and is moved from a bonding molecular orbital to an antibonding orbital since there is no longer an overall stabilizing interaction.

<h3>What is an antibonding orbital?</h3>

An antibonding molecular orbital is the molecular orbital created by the destructive overlapping of atomic orbitals.

<h3>Why is it called antibonding orbital?</h3>
  • Every atom will add one electron to the bond that makes up the lower energy bond.
  • To prevent interacting with the other two electrons, the additional electron will occupy a higher energy state.
  • The antibonding orbital is the name of this higher energy orbital.

<h3>What orbitals form an antibond?</h3>
  • The bonding orbitals are home to electrons that spend the majority of their time between the nuclei of two atoms, whereas the antibonding orbitals are home to electrons that spend the majority of their time outside the nuclei of two atoms.

<h3>When an electron was elevated to the antibonding orbital, what happened?</h3>
  • In contrast, putting electrons in antibonding orbitals will make the molecule less stable.
  • The energy levels of the orbitals will determine how many electrons are filled.
  • The lower energy orbitals will be filled first, and then the higher energy orbitals.

Answer:

20.95 g of caffeine, C₈H₁₀N₄O₂

Explanation:

From the question given above, the following data were obtained:

Number of molecules of C₈H₁₀N₄O₂ = 6.5×10²² molecules

Mass of C₈H₁₀N₄O₂ =?

From Avogadro's hypothesis,

1 mole of C₈H₁₀N₄O₂ = 6.02×10²³ molecules

Next, we shall determine the mass of 1 mole of C₈H₁₀N₄O₂. This can be obtained as follow:

1 mole of C₈H₁₀N₄O₂ = (8×12) + (10×1) + (4×14) + (2×16)

= 96 + 10 + 56 + 32

1 mole of C₈H₁₀N₄O₂ = 194 g

Thus,

194 g of C₈H₁₀N₄O₂ = 6.02×10²³ molecules

Finally, we shall determine the mass of caffeine, C₈H₁₀N₄O₂ that contains 6.5×10²² molecules. This can be obtained as follow:

6.02×10²³ molecules = 194 g of C₈H₁₀N₄O₂

Therefore,

6.5×10²² molecules = (6.5×10²² × 194) / 6.02×10²³

6.5×10²² molecules = 20.95 g of C₈H₁₀N₄O₂.

Therefore, 20.95 g of caffeine, C₈H₁₀N₄O₂ contains 6.5×10²² molecules
