Answer:
Mass of KCl = 7.45g
Molecular wt of KCl= 39+35.5=74.5g
Moles of KCl =

Answer:
A solution of potassium chloride was prepared by dissolving 2.5 g of
potassium chloride (KCl) in water and making the volume up to 100 cm3. Find the concentration of solution in mol/ dm3.
Molarity =(Mass of solute in gram)/(volume of solution in dm3)
Molarity =(2.5 gram)/(100 dm3)
Molarity=0.025 mol/ dm3
