Discover how much nitrogen gas weighs in grams per liter under standard temperature and pressure (STP).

93 views

A liter of nitrogen gas at standard temperature and pressure (STP) weighs approximately 1.25 grams. This data is based on the molar mass of nitrogen (approximately 28 grams per mole) and the volume occupied by one mole of gas at STP conditions (22.4 liters). Keep in mind, this value can vary slightly under different pressure and temperature conditions.
