Many combustible fuels have been given octane ratings,numbers that determine how suitable the fuel is as a gasoline forautomobiles. Regular unleaded gasoline has an octane rating of 89.Octane ratings are reported in tables for reference:
Fuel additive Octane rating heptane 0 hexane 25 pentane 62 isooctane 100 benzene 106 ethanol 108 p-xylene 116 toluene 118
Fuel additive Octane rating
----------------------------------------------
heptane 0
hexane 25
pentane 62
isooctane 100
benzene 106
ethanol 108
p-xylene 116
toluene 118
(I JUST PUT IT TWICE IN CASE THE PICTURE ABOVE DIDN'T SHOWUP--IT'S THE SAME CHART!)
Big Ed's Gas Farm is advertising a new super antiknock gasolinethat is a blend of pentane and ethanol. If ethanol represents29.0% of the mixture, what is the octane rating of Big Ed's newgas?
ANSWER:
octanerating=______________
