"Sterileness" and "sterility" are both noun forms of "sterile," which means being free from living microorganisms, bacteria, or germs. However, "sterility" is much more commonly used than "sterileness" and most reputable dictionaries do not even recognize "sterileness" as a standard English word.

Sterility is a condition often associated with cleanliness and a lack of contamination. Imagine a hospital operating room where surgeons are preparing for a delicate surgery. The sterility of the operating room is crucial to prevent infection and ensure the safety of the patient. All the instruments and surfaces in the room have been meticulously cleaned and sterilized to eliminate any potential pathogens. In this context, "sterility" describes the critical quality of the operating room being completely free from harmful microorganisms to maintain a safe and sanitary environment for the medical procedure.

Because "sterility" is more widely accepted than "sterileness," it would be a safe choice to use "sterility" in formal writing over "sterileness." Below are examples of "sterility" in sentences.
