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

There are different kinds of audio instrument. The speaker in the audio was en una tienda de ropa.
<h3>What are sound instruments?</h3>
All musical instruments are known to bring about sound. This makes matter to vibrate. The vibrations are known to bring about sound waves moving through the air.
A lot of musical instruments often uses resonance to make or increase the sound waves and make the sounds too be more louder. The voice in the audio is said to be that of en una tienda de ropa
