Elon Musk is trying to figure out how much oxygen he needs to get to
Mars. He has already used the standard heats of formation to calculate
how much heat energy the combustion of kerosene will produce. He then
figured out how many moles of kerosene he needs to produce the amount
of heat energy required to get to Mars. How can he figure out how many
grams or liters of oxygen he needs? Use the following terms: LAW OF
CONSERVATION OF MASS, BALANCED CHEMICAL REACTION.
STOICHIOMETRY, MOLE-TO-MOLE RATIO

Read these sentences from the text. near the equator, the tropics receive the most rain on a consistent basis. as a result, the fresh water falling into the ocean decrease the salinity of the surface water in that region. [. .] . . as the salt content of sea water increases, so does its density. what can you infer about how rain affects the density of surface water near the equator?
