After the dillution of the solution, the wavelength of maximum absorption is decreased.
<h3>What is the wavelength of maximum absorption?</h3>
The wavelength of maximum absorption is the wavelength at which the solution absorbs the maximum amount of light. It is usually shown as a hump in the spectrum.
When the starting concentration of the K2Cr2O7 is diluted, the wavelength of maxium absorption decreases.

Given the data from the question, the number of aluminum atoms in aluminum oxide, Al₂O₃ is 2 (Option B)
<h3>Composition of aluminum oxide, Al₂O₃</h3>
From the formula of the compound, Al₂O₃ we see that the compound is composed of
<h3>How to determine the number of aluminum atoms </h3>
- Formula of compound = Al₂O₃
- Number of oxygen atoms j= 3 × 1 = 3
- Number of aluminum atoms = 2 × 1 = 2
From the above, we can conclude that Al₂O₃ contains 2 atoms of aluminum.
