Seawater contains much more than just salt (sodium chloride). You can find the details in the Wikipedia article on "Seawater", but here's the summary.
The salinity of seawater varies with location and time, but on average it contains about 3.5% of dissolved solids by weight, or 35 grams per kilogram. About 19.25 grams are Cl-, chloride (chlorine in its -1 valence) and 10.7 grams are Na+, sodium in its +1 valence. The rest is sulfate (the SO4- - ion), 2.7 grams; Mg++ (magnesium), 1.3 grams, calcium, potassium and other minor ingredients.
The gram formula mass of NaCl is 58.44. By definition, a gram formula mass of a compound contains Avogadro's Number, about 6.022 X 1023 units, of the compound, and in sodium chloride, each unit contains two ions. The number of ions in 1 g is therefore 2(1/58.44)(6.022 X 1023), or 2 X 1022, to the justifiable number of significant digits.
The concentration of salt in ocean water is about 3.5% by weight. Therefore, 1 kg of salt would be in approximately 28.57 kg (or 28.57 liters) of seawater.

Which contains more heat 1kg of water at 0 degree or 1kg of ice at 0 degree give reason?
liquid water. its already melted.
What volume is 1kg of water?
1 kg of water has a volume of approximately 1 liter.
How do you find percent of salt per weight Example Water Level 6417 feet above sea level Salt Content 51.3 grams per liter One liter weight 1kg or 1000 grams?
To find the percent of salt by weight in the water, you need to calculate the total weight of the salt in the water. Since the salt content is 51.3 grams per liter and you have 1 liter of water, the weight of salt in the water is 51.3 grams. To find the percentage, divide the weight of the salt by the total weight of the solution (1000 grams for 1 liter of water) and multiply by 100. Therefore, the percent of salt by weight in this example would be 5.13%.
Why mass of water is equal to its volume?
The mass of water is equal to its volume because the density of water is approximately 1 gram per cubic centimeter. This means that 1 milliliter of water has a mass of 1 gram. Therefore, if you know the volume of water, you can easily determine its mass.
What tool can be used to measure the volume of an irregular solid object?
To find the volume of a solid you can't simply calculate, get a large tub of water in which you can completely immerse the solid. Fill the tub with water to the edge, then submerge the solid. Any water that spills over has been replaced by the solid and signifies the amount of space the solid is now taking up. Weigh the water or put it in 1l bottles. 1kg of water is 1l and a liter is a cubic decimeter. From there you can calculate the volume in any unit you want.
What refers to the number of grams of dissolved salts in 1kg of ocean water?
How much salt is in 1kg of water
Which do you think contains more matter and occupies more space 1kg of iron or 1kg of cotton?
1kg of iron contains more matter and occupies less space than 1kg of cotton. Iron is denser than cotton, so it has a higher mass-to-volume ratio.
Does salt kill roaches?
salt contains Na(sodium) ...sodium is present in body of cockroaches...so even if put 1kg of salt it wont die
Which contains more heat 1kg of water at 0 degree or 1kg of ice at 0 degree give reason?
liquid water. its already melted.
How much does a cup of water weight?
It depends on the volume of the cup. 1L of water weighs 1kg.
What is the volume of 1kg of ice?
The volume of 1kg of ice is approximately 0.916 liters.
What is the greater volume 1kg of copper or 1kg of gold?
1kg of gold has a greater volume than 1kg of copper because gold is denser and heavier than copper.
How much does steam expand?
Water weighs 1kg per liter. If it is all turned to steam you will have 1kg of steam. Water expands to nearly 1700 times its original volume at 212 degrees.
What is the volume of 1kg stone?
Without knowing the density of an object, it's not possible to calculate it's volume by weight. A 1kg piece of granite and a 1kg piece of igneous rock would be very different in volume.
What is the volume of 1kg of Nitrogen?
1.237
What volume is 1kg of water?
1 kg of water has a volume of approximately 1 liter.
Is 1kg feathers equal to 1kg stones?
Yes, 1kg of feathers is equal in weight to 1kg of stones. However, since feathers are less dense than stones, the volume of 1kg of feathers will be much larger than the volume of 1kg of stones.
