if 58.44 g of sodium chloride is dissolved in 0.5 liter of water what is the molarity of the sodium chloride solution? The molar mass of sodium chloride is 58.44 grams per mole.

so you have one mole in half a liter which is 2 moles per liter
Molarity=number of moles(n)/volume
also n=mass(m)/molar mass(M)
therefore,
Molarity(C)=mass/molar mass*volume
C=58.44g/0.5L(58.44g/mol)
C=2moles per litre
also n=mass(m)/molar mass(M)
therefore,
Molarity(C)=mass/molar mass*volume
C=58.44g/0.5L(58.44g/mol)
C=2moles per litre
