Question
Which one of the following is correct according to the STP conditions of gases?
- 0oC and 273K
- 273K and 760torr
- 760 torr and 760 mm Hg
- 0oC and 760 torr
Hint:
Standard temperature and pressure (STP) are standard sets of conditions for experimental measurements.
The correct answer is: 0oC and 760 torr
Standard temperature and pressure (STP) are standard sets of conditions for experimental measurements to be established to allow comparisons to be made between different sets of data.
STP as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 100,000 Pa/ 760 torr (1 bar, 14.5 psi, 0.98692 atm).
