According to the Wikipedia article on "Seawater": "Average density at the surface is 1.025 g/ml...", so that would be about 2.5% more than normal water, which has a density ver close to 1.

If freshwater and seawater meet at the mouth of a river which one sinks and why?

Seawater is more dense than freshwater. Therefore the seawater would sink lower than the freshwater. Ships do indeed stay higher in seawater because of the higher density or specific gravity of seawater over freshwater


Seawater is different to freshwater because it contain?

higher levels of salt and other minerals, making it more saline than freshwater. Seawater also has different organisms and ecosystems adapted to its unique conditions compared to freshwater environments. Additionally, seawater has a higher density and freezing point compared to freshwater.


Why are the concentrations of metals higher in freshwater than seawater?

The concentrations of metals are typically higher in freshwater than in seawater because freshwater systems have less capacity to dilute or transport metals compared to seawater. In freshwater systems, metals can be sourced from natural weathering of rocks and human activities, and they accumulate as there is less water volume to disperse them. Conversely, in the vast volume of seawater, metals are more dispersed and diluted.


Does salt content of water affect the density of seawater?

the salt makes seawater denser than freshwater. more salt increases the density


Is seawater a better conductor of electrcity than water from a freshwater lake?

Yes, seawater is a better conductor of electricity than water from a freshwater lake. This is because seawater contains a higher concentration of dissolved ions, such as sodium and chloride, which allow for the flow of electrical current more easily compared to freshwater that has fewer dissolved ions.


Does a liter of feathers weigh more then a liter of gold?

no!


Why sea water has a higher hydrometer reading than that of freshwater?

Seawater dissolves more than fresh water because of the salinity in the water.


Is there more oxygen in seawater or air?

There is more oxygen in seawater. Seawater contains around 5 to 10 milligrams of oxygen per liter, while the concentration of oxygen in the air is about 210 milligrams per liter. However, the total amount of oxygen in the oceans is much higher due to their vast volume.


What are the two major aquatic systems?

I believe its marine & freshwater ecosystems


How much does 1 liter of salt water weigh in kg?

The density of seawater varies from 1020 to 1029 kg/cubic meter, with 1027 kg/cubic meter being cited most often for water at the ocean's surface. There are 1,000 liters per cubic meter, so the density of seawater can also be expressed as 1.027 kg/liter (for surface seawater). Thus 1 liter of seawater will weigh 1.027 kg.


What happens when saltwater and freshwater meet?

It is not clear what you are asking. Perhaps this will help. !f you take a liter of pure fresh water and weigh it, it will weigh 1000 grams (a kilogram). If you then add 10 grams of salt to the water and stir the salt until it has all dissolved and measure the volume of the now salty water, the volume of the salt water will still measure exactly one liter. However if you weigh the liter of salt water it will weigh 1010 grams. This means that there are now more particles (atoms) occupying the same space - the DENSITY of the salt water is higher than the fresh water.
