A small portion of gaseous gasoline (boiling point of gasoline: ~185 oF, it becomes gas at 212 oF) was then injected to mix with air in the container(total mass of air=.892) , according to air/fuel ratio (14.7:1 by mass). Consider 90% mass of gasoline is isooctane and the rest is ethanol (C2H6O), how much are isooctane and ethanol in moles added, respectively? With the amount of gasoline injected, what is new total pressure of the container?

A small amount of gaseous gasoline is added into a container to mix with air (air is at 212 F). The air to fuel ratio is 14.7:1 by mass. Note that the boiling point of gasoline is ~185 F, and it becomes gas at 212 F. 90% of the mass of gasoline is isooctane and the remaining is ethanol (C2H6O). How much of isooctane and ethanol in moles has been added to the container? With the amount of gasoline added,...

i need help with the postlab questions please Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
