A student is given a sample of a calcium sulfate hydrate. He places the sample in a dry, covered crucible and weighs it. The total mass (crucible, cover, and hydrate) is 19.39219.392 g. The crucible and cover together had previously weighed 17.98717.987 g. He then heats the crucible to redness for 10 minutes with the cover slightly ajar. After the crucible cools, he weighs the crucible and its contents; the mass is now 19.09819.098 g, due to the loss of...

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,...
