Pretty concentrated! ( I assume you mean 2.3 Liters )
First get the moles of sodium chloride.
456 grams NaCl (1 mole NaCl/58.44 grams)
= 7.803 moles NaCl
==============
Now,
Molarity = moles of solute/Liters of solution
Molarity = 7.803 moles NaCl/2.3 Liters
= 3.4 M NaCl solution

What is the concentration M of a NaCl solution prepared by dissolving 3.8 g of NaCl in sufficient water to give 245 mL of solution?
Get moles NaCl and change 245 ml to 0.245 Liters. 3.8 grams NaCl (1 mole NaCl/58.54 grams) = 0.0650 moles NaCl Molarity = moles of solute/Liters of solution Molarity = 0.0650 moles NaCl/0.245 Liters = 0.27 M NaCl ----------------------
