Usually it would be the second or third time you say it
Assumption of risk..............
All of above should be if but if not on there it will be the first one
I think the answer here is D. A seems wrong because it involves your opinion as a writer which should not be involved in a description. B is wrong because you should always assume that the reader knows nothing about the subject when writing a description. C is wrong because all steps should be outlined in a description. Finally, D is correct because a description should be detailed and easy to follow. Hope that helps!
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
