How many grams of sodium chloride is in 0.40 moles?

Answer 1

Molarity = moles of solute/Liters of solution ( 300 ml = 0.300 Liters )

For our purposes, Moles of solute = Liters of solution * Molarity

Moles NaCl = 0.300 Liters * 0.15 M

= 0.05 moles NaCl

=============

Answer 2

Molarity = moles of solute/Liters of solition

(300 ml = 0.300 Liters )

0.40 M NaCl = moles NaCl/0.300 Liters

= 0.120 moles NaCl

Answer 3

0.40 moles NaCl (58.44 grams/1 mole NaCl)

= 23 grams sodium chloride
