The value of kb of cyclohexane in the given question is; kb = 2.82 °C/m
<h3>Understanding Molality of a Solution</h3>
Molality of solution = (Number of moles of C₆H₄Cl₂)/(Mass of Cyclohexane)
Now;
Number of moles of C₆H₄Cl₂ = Mass/molar mass = 2g/147 g/mol
Number of moles of C₆H₄Cl₂ = 0.0136 mol
Molality of solution = 0.0136/(22.5 * 10⁻³ kg)
Molality of solution = 0.6 m
Now, to find kb for cyclohexane, we will use the formula;
T_b(solution) - T_b(solvent) = kb × molality of solution
Thus;
82.39 - 70 = kb * 0.6
kb = (82.39 - 70)/0.6
kb = 2.82 °C/m

Choosing a university career was a very significant decision because it determined my field of work for the rest of my life.
<h3>What is a decision?</h3>
A decision is a term to refer to the result of a specific mental-cognitive process in which one option in a variety of options is decided to obtain a beneficial result.
Humans are making decisions at all times and it is an innate function of our brain to make decisions and prefer one option over the others to obtain a benefit.
Additionally, some decisions are more significant than others because of the result they trigger in a person's life. For example, the decision to choose a university career is more significant than the decision of what to eat for lunch.
According to the above, some examples of significant decisions are:
- Have or not have a child.
- Study a university degree.
- Travel to another country.
- Get a job.
- Create your own company.
- Invest in a business.
- Buy a house.

Explanation:
Sir Isaac Newton is buried at Westminster Abbey in London.
<u>Queen Elizabeth I</u> is most likely to also be buried there.
<h3>Who is
Sir Isaac Newton?</h3>
Isaac Newton, or Sir Isaac Newton, was an English physicist and mathematician who was the pinnacle of the Scientific Revolution of the 17th century. Newton was born in Woolsthorpe, Lincolnshire, England, on December 25, 1642 (or January 4, 1643, New Style), and died in London on March 20 [or March 31, 1727].
His understanding of the nature of white light in optics helped to incorporate the color-related phenomena into the study of light and laid the groundwork for contemporary physical optics. The law of universal gravitation was developed in mechanics as a result of his three laws of motion, which are the cornerstones of contemporary physics.
