Need help, please. Assume that you are traveling to an unknown planet. Ammonia plays a role similar to water on Earth. Given the following information, complete the following questions.\[ T_b^o = -33.4 \, ^\circ \text{C}, \Delta H_{\text{vap}} = 23.35 \, \text{kJ/mol}, T_f^o = -77.7 \, ^\circ \text{C}, M = 17.03 \, \text{g/mol} \]a. Estimate the temperature at which the vapor pressure of ammonia is 60 torr. (Hint: 760 torr = 1 atm).b. Calculate the entropy of vaporization of ammonia at its normal boiling point.c. When 1.00 mol of ammonia chloride, \( \text{NH}_4\text{Cl} \) is dissolved in 1.00 kg of liquid ammonia, the boiling point at 760 torr is observed to occur at \( -32.7 \, ^\circ \text{C} \). Compute the boiling point elevation constant for \( \text{NH}_3 \).

As per Clausius-Clapeyron Equation,Let T1 be the boiling point.Therefore,T1 = -33.4 C = -33.4 C +273.15 K = 239.75KAs per given conditions, At boiling point, Vapour pressure = 1atm.P1 = 1 atmP2 = 60 torr = 60torr x 1/760 atm/torr = 0.07895atmPutting values in formula,we get,Therefore,at 76.22C vapour pressure = 60torr.Boiling point elevation is given by,m = Moles of Solute / Mass of solvent in Kg = 1mol/1Kg = 1mol/Kgi = 2 for ammonium chloride since it dissociates in two ions.Therefore,0.7C = 2 x 1mol/Kg x KbKb = 0.7C/(2 x 1mol/Kg)Kb = 0.35mol/Kg.CAnswers for the given problem are provided in the steps.
