To solve for the concentration (in molarity) of the brine solution, we can use this formula:

`molarity = (mol es of NaCl)/(Liters of solution)`

To get the moles of any compound, divide the given mass by its molar mass. 

`mol es NaCl = (225 grams NaCl)/(58.44 (grams)/(mol e))`

`mol es NaCl = 3.8501 mol es NaCl`

 

Finally, we can solve for the concentration of the brine solution:

`molarity = (3.8501 mol es NaCl)/(4.00 Liters of solution)`

 

`molarity = 0.963 (mol es)/(L)`
