# What is the molarity of a solution prepare2.3 Ld by dissolving 456 g NaCL in?

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
