The heat of vaporization ΔHᵥ of diethyl ether ((CH₃)₂(CH₂)₂O) is 26.7 KJ/mol. Calculate the change in entropy Δs when 3.4 g of diethyl ether condenses at 34.6 °C.
Be sure your answer contains a unit symbol and the correct number of significant digits.

ΔS = 4.1 J/K

Explanation:

Enthalpy (H) is defined as the amount of energy released or absorbed during a chemical reaction.

Entropy (S) defines the degree of randomness or disorder in a system.

The relationship between both parameters is given as;

ΔS = ΔH / T

ΔH = 26.7 KJ/mol for 1 mol of diethyl ether

number of moles = mass / molar mass

number of moles = 3.4 / 72 = 0.04722

ΔH = 26700 * 0.04722 = 1260.77 J

T = 34.6 + 273 = 307.6 (upon converting to kelvin temperature)

ΔS = 1260.77 / 307.6

ΔS = 4.1 J/K

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
