What is STP in torr?
Standard Temperature and Pressure. Standard temperature is equal to 0 °C, which is 273.15 K. Standard Pressure is 1 Atm, 101.3kPa or 760 mmHg or torr. STP is the “standard” conditions often used for measuring gas density and volume. At STP, 1 mole of any gas occupies 22.4L.
What is STEX apex?
For chemistry, IUPAC established standard temperature and pressure (informally abbreviated as STP) as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of 101.325 kPa (14.7 psi, 1.00 atm, 1.01325 bar).
What is gram molar volume?
The gram molecular volume is the volume occupied by one mole of ideal gas at STP. It is equal to 22.4 L.
What is STP in Kelvin and kilopascals?
STP is defined as 273.15 K and a pressure of exactly 100 kPa (1 bar).
How do you convert Kelvin to atm?
Divide the result by the number of moles of gas. If, for instance, the gas contains 2 moles of molecules: 20 / 2 = 10. Divide the result by the gas constant, which is 0.08206 L atm/mol K: 10 / 0.08206 = 121.86. This is the gas’s temperature, in Kelvin.
