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?

Suppose you wanted to make 100 grams of water. what is the molar mass of water (h2o)?

Find the mass, in grams, of 5.00*10^23 molecules of f2
