Answer:

Mass of KCl = 7.45g

Molecular wt of KCl= 39+35.5=74.5g

Moles of KCl =

74.5

7.45

=0.1

Molarity =  

massofsolvent(inkg)

moles

=  

100×10

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
