10b ### Understanding Standard Temperature and Pressure (STP)**STP (standard temperature and pressure)** is utilized as a reference point for determining the molar volume of an ideal gas. In the United States, most chemists, general chemistry texts, and the OWL platform adopt:- **STP = 0°C, 1 atm**, where the **molar volume = 22.4 L/mol**.It's important to note that if the reference pressure used is 1 bar, the molar volume changes to **22.7 L/mol**. Be cautious not to confuse these two cases.#### Sample CalculationA **1.31 mol** sample of **hydrogen gas** occupies a volume of **[ ] L** at STP.This example highlights the calculation of gas volumes under standardized conditions, emphasizing the importance of using consistent STP definitions in scientific measurements and discussions.

In the USA, most chemists, most general chemistry texts, and OWL use STP = 0°C, 1 atm, where the molar volume = 22.4 L/mol. If the reference pressure is chosen to be 1 bar, the molar volume is 22.7 L/mol. Do not confuse the two. A 1.31 mol sample of hydrogen gas occupies a volume of L at STP.
