Ethyl chloride,C₂H₅Cl,is used as a local anesthetic.It works by cooling tissue as it vaporizes;its heat of vaporization is 26.4 kJ/mol.How much heat could be removed by 20.0 g of ethyl chloride? A)8)18 kJ B)341 kJ C)528 kJ D)3410 kJ

Question

Quizplus · Accepted Answer

The molar mass of ethyl chloride (C2H5Cl) is approximately 64.5 g/mol. Therefore, 20.0 g corresponds to about 0.31 mol. The heat removed is calculated by multiplying the moles by the heat of vaporization: 0.31 mol * 26.4 kJ/mol = 8.18 kJ.
