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

Dear foriener friend,
I am writing this letter for you. I live in Nepal.Nepal is a place where I was born and I live in.Nepal is a beautiful country.Nepal is also the most beautiful country in the world too.Our country is divided into three groups they are terai region,mountain region and hilly region.Here are many population growth of people in our country.Here is so many beautiful places to visit for tourists to visit.Nepal is als rich in nature and water.Here are many beautiful houses,places and shops.In our country here are many facilities and rights for all of us.Here people celebrate different festivals that depends on their religions,cast and culture.Here are total altogether 135 ethnic groups and 123 languages are spoken here.Here they sell do hard work for their life to survive,to make their family happy, to protect their family,to fulfill their needs and to fulfill their dreams.Now,our country is developed much more and better than before.And I love my country very much.

Answer:One factor that enabled the Renaissance to flourish in Northern Italy was that the region had a wealthy class that invested in the arts. During this period, there were many rich families that heavily invested and supported artworks and their artists. One of the most prominent families at the time was the Medici family who were benefactors of artists like Michelangelo and Botticelli.
Explanation:
Probability distributions are used to represent data and their probabilities
The table entry is given as:
<u>Age of House Number of Houses</u>
1 15
2 20
3 25
4 30
Start by calculating the probability of selecting a house that has a certain age.
This is calculated as:
So, we have:
This means that the graph that represents the probability distribution must show that the probability of 1 is 0.17; 2 is 0.22; 3 is 0.28; 4 is 0.33.
