Problem 116E

When a suspected drunk driver blows 188 mL of his breath through the fuel-cell breathalyzer described in Section 18.7 , the breathalyzer produces an average of 324 mA of current for 10 s. Assuming a pressure of 1.0 atm and a temperature of 25 o

C, what percent (by volume) of the driver’s breath is ethanol?

Step-by-Step Solution:

Problem 116EWhen a suspected drunk driver blows 188 mL of his breath through the fuel-cellbreathalyzer described in Section 18.7, the breathalyzer produces an average of 324 mA ofcurrent for 10s. Assuming a pressure of 1.0 atm and a temperature of , what percent(by volume) of the driver's breath is ethanol Step by step solutionStep 1 of 5From the given,Volume of the breath from the suspected drunk driver = 188 mLThe current produced in breathalyzer = 324 mASince total current produced = 0.324 ATime = 10 sTherefore the total charge passes through the breathalyzer, = 3.24 C
