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.

Answer 1

so you have one mole in half a liter which is 2 moles per liter

Answer 2

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
