Blood is far denser than sea water as it has a whole bunch of cellular bodies mixed in with it. I think you wanted to ask "Which is denser seawater or serum?" In that case serum is still heavier even though it has less salt. Serum still has a wide assortment of exotic proteins dissolved in it.
sulfate
Motor oil will float on water. That makes water denser.
Gasoline floats on water and is therefore less dense than water. Eggs sink in water and are therefore denser than water. A process of logical deduction will therefore show you that Eggs are DENSER than Gasoline. Your question therefore makes no sense.
actually it's not. seawater has a pH of 8 making it a base.
the salt makes seawater denser than freshwater. more salt increases the density
Seawater because it contains salt which makes the water more dense than water which does not contain salt.
Salt
riptide
yes because of the salt
Nope; specific gravity is lower

probally fresh because no salt in mouth or eyes addition: it is easier to float/swim in seawater since seawater is denser than fresh water.
You have it backwards. A ship floats higher in seawater than freshwater. This is because the dissolved salt makes seawater denser. due to the lack of salt content in fresh water. the salinity of ocean water makes it more dense, allowing the boat to sit higher in the water.
sea water is less denser than river water.
Sodium chloride is the most important salt in the seawater.
Because sand is denser than water. But I suspect you meant to ask "why is it easier to stay afloat in seawater than it is in fresh water". In which case the answer is the same: seawater is denser ... but not as dramatically, and the difference is small enough that you're unlikely to actually notice it unless you take careful measurements.
