What does solution per liter of vinegar mean?

[FLgirl]

I'm trying to find out:

-Mass (g) of acetic acid per liter of vinegar and
-Mass (g) of solution per liter of vinegar

I thought mass (g) of solution meant how much acetic acid but apparently not? what does it mean and how do I calculate it? Thanks :)

i believe that vinegar is the solution. so you just take the density of vinegar and scale it up to a liter.
