The local anesthetic ethyl chloride ( C2H5Cl, molar mass = 64.50

g
- according to the following balanced equation:

can be prepared by the reaction of ethylene ( C2H4, molar mass = 28.05

hydrogen chloride ( HC1, molar mass = 36.45

C2H4 + HCI -+ C2H5Cl

Assuming 14.00 g of ethylene and 24.00 g of hydrogen chloride are used, answer the following questions:
How many moles of hydrogen chloride are used? Be sure your answer has the correct number of significant figures.

moles of hydrogen chloride =

mol HC1
