Find the mola...

Question

Find the molarity of 0.585 Gram NaCl present in 500 ml of solution??

Open in App

Solution

Molarity=no:of moles of solute /volume of solution in liter
No :of moles = weight of solute / molecular mass of solute
Molecular mass= 58.5 g
Weight of solute =0.585
No :of moles of solute=0.585/58.5= 0.01 mole
Volume off solution =500 ml =0.5 L
Molarity = 0.01/0.5=0.02 mol per litre
