Based on the calculations, the mass of Aluminum in 4.85 × 10²² atoms is equal to 2.1762 grams.
<h3>How to calculate the mass of Aluminum?</h3>
In order to determine the mass of Aluminum, we would calculate the number of atoms in 1 mole of an Aluminum atom in accordance with Avogadro's constant.
1 mole of Aluminum atom = 6.02 × 10²³ molecules
X moles of Aluminum atom = 4.85 × 10²² molecules
Cross-multiplying, we have:
X = 4.85 × 10²²/6.02 × 10²³
X = 0.0806 moles.
Mass = Molar mass × Number of moles
Mass = 27 × 0.0806
Mass = 2.1762 grams.

The answer is "C" because all isotopes have a different mass number. The number of protons does not change. The mass of electrons is negligible. Thus, the number of neutrons changes.
<span>under specific conditions it can promptly be taken apart easily, yielding a great deal of energy . It is subsequently said to be 'fissile' and we utilize the articulation 'atomic splitting'. In the interim, similar to every single radioactive isotope, they rot.</span>
