Number of moles of KOH present in solution is 3.75.
<h3>What do you mean by mole concept?</h3>
The term "mole" refers to a mole's atomic mass, which is expressed in grams. A mole is an element's gram-atomic mass, or mass.
The mole idea equates the mass of a single atom or molecule (measured in a.m.u.) to the mass (measured in grams) of a large collection of equivalent molecules.
To calculate moles of potassium hydroxide in 750 ml of 5.00 m of KOH solution -
Mathematically molarity is expressed as,
Molarity =no. of molecules of solute/volume of solution
Given: Molarity of solution = 5.00 M
Volume of solution = 750 ml = 0.750 l
∴ 5 = no. of moles/0.750
∴ number of moles = 3.75
Hence, number of moles of KOH present in solution is 3.75.

Answer:
Answer
The limitations are-
1. Privacy of the individuals involved in the research process.
2. Physical and psychological risks should be minimized
3. The subjects should be chosen equitably
4. Only reasonable exposure to risks is admissible.
Explanation
The privacy of the individuals involved in the research must be taken into consideration. This will ensure safety of patient data and information. The risk of physical and physiological well being of the person must be taken into consideration in such a research. In addition to that, the subject must be made to understand every procedure and the risks involved before testing. Moreover, only minimal exposure to risks is allowed and must have been previously tested in animals to avoid deaths.
