Problem 62AE

Ethyl chloride is sold as a liquid (see photo) under pressure for use as a local skin anesthetic. Ethyl chloride boils at 12 °C at atmospheric pressure. When the liquid is sprayed onto the skin, it boils off, cooling and numbing the skin as it vaporizes, (a) What changes of state are involved in this use of ethyl chloride? (b) What is the boiling point of ethyl chloride in degrees Fahrenheit? (c) The bottle shown contains 103.5 ml of ethyl chloride. The density of ethyl chloride at 25 °C is 0.765 g/cm3. What is the mass of ethyl chloride in the bottle?

Step-by-Step Solution:

Problem 62AEEthyl chloride is sold as a liquid (see photo) under pressure for use as a local skinanesthetic. Ethyl chloride boils at 12 °C at atmospheric pressure. When the liquid issprayed onto the skin, it boils off, cooling and numbing the skin as it vaporizes, (a) Whatchanges of state are involved in this use of ethyl chloride (b) What is the boiling point ofethyl chloride in degrees Fahrenheit (c) The bottle shown contains 103.5 ml of ethylchloride. The density of ethyl chloride at 25 °C is 0.765 g/cm . What is the mass of ethylchloride in the bottleAnswerStep 1 of 3(a)The molecular formula of ethyl chloride is C H Cl. 2 5Ethyl chloride is also known as chloroethane or monochloroethane.Under pressure,ethyl chloride is packed as a liquid in the container. The pressure escapes asreleased from the container, and the liquid ethyl chloride is turned into vapor form. Here, thetransition in condition is from liquid to gas.As the pressure is reduced, the molecules evaporate into a vapor form that results in theappearance of cooling or numbering effect on the skin.
