There are 4 energy sublevels are present in the principal energy level n = 4.
<h3>What is sublevels?</h3>
Sub-level is a type of level that is lower than another level or it is a part or component of a big level. S, p, d and f are the four energy levels in which electrons are present.
So we can conclude that 4 energy sublevels are present in the principal energy level n = 4.

Answer:
Explanation:
Given
Required
Determine the final mass
First we need to determine the total mass after the sample mass is added to an additional sample;
Next, divide the total mass by 3
The final mass is calculated as follows;
<em>Hence, the final mass is 17.560943085g</em>
Molecular formula: C10H15Cl5
C. Six ammonia molecules are formed, with zero molecules remaining.
