QUESTION: Problem 89P

Physicians who specialize in sports medicine routinely treat athletes and dancers. Ethyl chloride, a local anesthetic commonly used for simple injuries, is the product of the combination of ethylene with hydrogen chloride:

C2H4(g) + HCl(g) →C2H5Cl(g)

If 0.100 kg of C2H4 and 0.100 kg of HCl react:

(a) How many molecules of gas (reactants plus products) are present when the reaction is complete?

(b) How many moles of gas are present when half the product forms?
