Advanced Standard Temperature and Pressure Calculator

An Advanced Standard Temperature and Pressure (STP) calculator is used to compute properties of gases, particularly under standard conditions. Standard Temperature and Pressure (STP) typically refer to:

  • Standard Temperature (T) = 0°C or 273.15 K
  • Standard Pressure (P) = 1 atmosphere (atm) or 101.325 kPa

If you want to calculate properties like volume, molar volume, or pressure of a gas at STP, you can use the ideal gas law equation:

PV=nRT

Where:

  • P = Pressure (in atmospheres, atm or kPa)
  • V = Volume (in liters or cubic meters)
  • n = Number of moles of gas
  • R = Ideal gas constant (0.0821 L·atm/(mol·K) or 8.314 J/(mol·K))
  • T = Temperature (in Kelvin)

Common STP Calculations:

  1. Volume of Gas at STP: If you know the number of moles of a gas at STP, you can calculate its volume at STP using the molar volume of an ideal gas, which is about 22.414 L/mol at STP.

    Formula:

    V=n×22.414 L/mol

  2. Pressure or Volume at STP (from the Ideal Gas Law): If you know the other properties (e.g., volume, number of moles, or pressure), you can rearrange the ideal gas law to solve for the missing variable.
