text: would you expect crude oil in an oil tanker to float or sink in the salty ocean water? and if u could and if u understand this question: what data would you need to answer this question?(the 1 above) (like the mass, volume, density,  r some other thin. (suppose 2 be inside the results in a data table r sometin)) data needed: density of salt solution density of oil  what the crude oil actually consisted of, because some of the components of crude will sink while other parts of it floats like a big nasty sloppy mess!
