Acanadian, driving in the u. s.a., fuels their car at a cost of us$3.82 per gallon (us). the current monetary exchange rate is 0.942 us$/can$. the density of the fuel is 0.674 g/ml. a) what is the mass of can$30.00-worth of this fuel? b) if the vehicle consumes the gasoline at a rate of 8.53 l/100 km, how many miles can it travel on the above amount of gasoline?

Steam reforming of methane ( ch4) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. an industrial chemist studying this reaction fills a 1.5 l flask with 3.5 atm of methane gas and 1.3 atm of water vapor at 43.0°c. he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 1 .0 atm. calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to 2 significant digits.
