What is the molar mass of KNO3?

The molar mass of KNO3, also known as potassium nitrate, is 101.1 grams per mole. This molecule exists as a single potassium ion and a single nitrate ion held together with an ionic bond.

Potassium nitrate exists as a solid, inorganic salt at room temperature. It's a strong oxidizing agent and can be flammable if exposed to other combustible agents. Potassium nitrate is harmful if ingested or applied to tissues and can cause gastrointestinal and eye damage. Commercially, potassium nitrate is used in a variety of products, including gunpowder and fireworks. It's also an additive in many fertilizers because both potassium and nitrate are nutrients that facilitate plant growth.
