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

<u>ANSWER:
</u>
Until the late 1800s, the purpose of secondary education in the US was a basic one where the children under all age groups were taught in a common room in the school. The students of secondary classes are meant to teach the primary ones.
<u>EXPLANATION:
</u>
- It has also been said that until the late 1800s, girls and minorities were not given admission to high schools for secondary education.
- During the late 1800s, Boston opened a public high school for girls so that women acquired an opportunity to learn secondary education.
