Pricing Rule : Give free items per quantity purchased

Hello Everyone,
I want to know that if it is possible to create a pricing rule or promotional scheme with the following idea:

  1. We want to give the free product on per quantity of item purchase .

for example :
if we have a promotional scheme where we give free item on purchase of 1 kg of our product .
now my requirement is that if 5 kg of that product is purchase we want to give 5 quantity of the free item.

How can I achieve this?
