Answer:
Stabilizer with area = 14 cm².
Step-by-step explanation:
Area of the wing = 101.25 cm²
Rule of the thumb is that area of stabilizer must be about 1/6 to 1/8 of the area of wing. So, first we calculate 1/6 of the area of the wing and 1/8 of the area of the wing. Area of stabilizer must be in between these two numbers.
1/6 of the area of wing = \frac{1}{6} \times 101.25 = 16.87561×101.25=16.875
1/8 of the area of wing = \frac{1}{8} \times 101.25 = 12.65681×101.25=12.656
This means, the area of horizontal stabilizer must be in between 12.656 cm² and 16.875 cm². From the given options only one option lies in between these two numbers and that is 14 cm²
Therefore, area of a good stabilizer design from the given options would be 14 cm²

Taking into account the definition of Avogadro's Number, 7.80×10²² molecules of HCl are contained in 0.1295 moles of HCl.
<h3>
Avogadro's Number</h3>
Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.
<h3>This case</h3>
Then you can apply the following rule of three: if 6.023×10²³ molecules are contained in 1 mole of HCl, then 7.80×10²² molecules are contained in how many moles of HCl?
amount of moles of HCl= (7.80×10²² molecules × 1 mole)÷ 6.023×10²³ molecules
<u><em>amount of moles of HCl= 0.1295 moles</em></u>
Finally, 7.80×10²² molecules of HCl are contained in 0.1295 moles of HCl.
