.

1000 mL of water is one liter.

Dissolution of 3.5 grams of salt in one liter of pure water practically does not change this volume.

            Again, salt is very special substance: dissolution of small and even
            moderate amount of salt in water practically does not change the liquid volume.

            This fact is known hundreds and thousand years from people' everyday practice.

            Students become familiar with this fact studying Science and later Chemistry.

So, in this case we can say that one liter of seawater contains 3.5 grams of salt.

About sea water (saline water) see this Wikipedia article
https://en.wikipedia.org/wiki/Seawater

Notice that typical salt concentration in seawater is about 3.5%.

It means that every liter and/or every kilogram of sea water contains about 35 grams (!) of salt.

        Not 3.5 grams per liter, as stated in your post (!) --- but much-much more (!)

From this article, you will learn many interesting things about the subject (!)

Reading Wikipedia articles is always useful, because it is a good source of knowledge (as a rule).

You will learn more about the world, in which you live (!)

Answer: 3.5 grams of salt

This is because 1000 mL = 1 liter
Saying "3.5 grams of salt per liter" is the same as saying "1 liter contains 3.5 grams of salt".
