Given:Sea water contains roughly 28.0 g of NaCl per liter.
To find: What is the molarity of sodium chloride (NaCl) in sea water?
Molecular mass of NaCl= 58.4
Therefore 1 mole of NaCl= 58.4 g
Number of moles in sea water= 28/58.4= 0.479
Therefore, 1 litre of water contains 0.479 moles of NaCl
Now, Molarity(M) = Number of moles of solute/ volume of solvent.
M= 0.479/1 = 0.479M
