What is the standard pressure condition for gases?
A
1.5 atm
B
110.23 kPa
C
760 mm Hg
D
460 Torr
Explanation: 

Detailed explanation-1: -Standard pressure-760 mm of Hg = 76 cm of Hg = 1 atmospheric pressure.

Detailed explanation-2: -Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1, 013.25 × 103 dynes per square centimetre, 1, 013.25 millibars, one standard atmosphere, or 101.325 kilopascals.

Detailed explanation-3: -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.

Detailed explanation-4: -NIST uses a temperature of 20 °C (293.15 K, 68 °F) and an absolute pressure of 1 atm (14.696 psi, 101.325 kPa). This standard is also called normal temperature and pressure (abbreviated as NTP).

Detailed explanation-5: -Standard pressure supports 760 millimeters in a mercurial barometer (760 mmHg) or 760 torr. This is about 29.9 inches of mercury, and represents approximately 14.7 pounds per inch (14.7 lb/in2).
