Computers in some vehicles calculate various quantities related to performance. One of these is the fuel efficiency, or gas mileage, usually expressed as miles per gallon (mpg). A particular vehicle equipped in this way is advertised as having a fuel efficiency of 41 mpg. A woman who owns one of these vehicles believes she is getting even higher fuel efficiency, so she recorded the mpg each time the gas tank was filled, and then reset the computer. For 18 recordings,...

Hydrogen is oxidized in a fuel cell to make electricity, by the (unbalanced) reaction: H2 + O2  H2O. 1 kg/min H2 is fed to the fuel cell, and oxygen is fed as 21% of air. The oxygen is fed at a rate 50% more than the minimum required to completely oxidize all the H2. Assuming that all the Hydrogen is consumed, find the molar flow rate of all chemical species leaving the fuel cell.
