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.

1. Damon

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

2. Jeffrey

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
