2 answers:
Answer: Option (d) is the correct answer.
Explanation:
A fatty acid is defined as a long chain of hydrocarbons that consists of a carboxylic group, that is, COOH group at the end of the chain.
General formula of a fatty acid is where n is mostly an even number in many cases.
Fatty acids are also known as aliphatic monocarboxylic acid.
For example, is the formula of stearic acid which is a fatty acid.
Thus, we can conclude that a long chain of hydrocarbon bonded to cooh is a fatty acid.

<h3>The answer is 4.65 moles</h3>Explanation:
To find the number of moles given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
N = 2.8 × 10²⁴ atoms of Cl2
So we have
We have the final answer as
<h3>4.65 moles</h3>Hope this helps you
Answer:
Explanation:
To start with, the mass of a substance is centered on the amount of particles contained in it.
Mass of a substance measure is the same anywhere it is taken.
In chemistry, the concept of mole is used to find the exact estimate of the number of entities in a sample.
A mole of substance is quantity that is used to express the number of particles contained in it.
1 mole of any substance contains the Avogadro's number of particles.
This amount of particles is given as 6.02 x 10²³; the particles can be protons, neutrons, electrons e.t.c.
To find the number of moles;
Number of moles =
Through this, we clearly ascertain the number of entities in a sample given the mass.
