Composition

There is more at sea salt, but 1 kg of salt water contains approximately

965.00g Water
 19.25g Chloride (Cl-)
 10.70g Sodium
  2.70g Sulfate (SO4-2)
  1.30g Magnesium
  0.42g Calcium
  0.39g Potassium
  0.0673g Bromide (Br-)
  0.24g Other

This means that there's approximately ½ mol of sodium chloride (29g) of salt in 1 liter of salt water, requiring 965g of water to be boiled (evaporated) away to obtain it.
