Ammonia, NH3, is used as a refrigerant. At its boiling point of –33 oC, the standard enthalpy of vaporization of ammonia is 23.3
mario62 [17]

Answer:

-68.4 kJ

Explanation:

<u>The standard enthalpy of vaporization = 23.3 kJ/mol</u>

<u>which means the energy required to vaporize 1 mole of ammonia at its boiling point (-33 °C).</u>

To calculate heat released when 50.0 g of ammonia is condensed at -33 °C.

This is the opposite of enthalpy of vaporization which means that same magnitude of heat is released.

<u>Thus,  Q = -23.3 kJ/mol</u>

<u>Where negative sign signifies release of heat</u>

Given: mass of 50.0 g

Molar mass of ammonia = 17.034 g/mol

Moles of ammonia = 50.0 /17.034 moles = 2.9353 moles

Also,

1 mole of ammonia when condenses at -33 °C releases 23.3 kJ

2.9412 moles of ammonia when condenses at -33 °C releases 23.3×2.9353 kJ

<u>Thus, amount of heat released when 50 g of ammonia condensed at -33 °C= -68.4 kJ, where negative sign signifies release of heat.</u>
