If I am a national one of the 80 countries eligible for Visa-Free entry into Qatar, what are the entry requirements?

The only entry requirements for nationals of the 80 countries entitled to visa-free entry are a valid passport (valid for a minimum of 6 months) and a confirmed onward or return travel ticket. 

You will also be asked to provide a valid address for your place of stay in Qatar (i.e., the address of your hotel, as shown on your booking, or the physical address of a friend or family member with whom you intend to stay). 

You are not required to \ produce evidence of adequate funding. However, Pakistani nationals coming on visa-free entry must be in possession of a valid credit card.
