The question is a bit unclear. It seems like you're asking about the concentration of a salt (NaCl) solution. However, it's missing some crucial information:

* What is the volume of the solution? You need to know the volume of the solution (in liters) to calculate the concentration in grams per liter (g/L).

* Is "2 soultion" a typo? It's likely meant to be "2 L solution" or something similar.

Here's how to calculate concentration if you have the volume:

1. Mass of solute: You have 80 g of NaCl (sodium chloride).

2. Volume of solution: You need to know the volume of the solution in liters. Let's assume it's 2 liters for this example.

3. Concentration:

* Concentration (g/L) = (Mass of solute (g)) / (Volume of solution (L))

* Concentration = 80 g / 2 L = 40 g/L

Therefore, if the solution volume is 2 liters, the concentration of the NaCl solution is 40 g/L.

Please provide the missing information (volume of solution) so I can give you a precise answer.
