These data are very variable around the world.
- IUPAC recommendations:
a) 0 oC and 100 kPa or
b) 25 oC and 100 kPa
- NIST recommendation:
20 0 oC and 101,325 kPa
- methane gas measurements: 15 oC
and other values also exist.
Standard temperature and pressure (STP) is a temperature 0ºC (32ºF) with the air pressure the same as at sea level.
It is one of the informal definitions for an outlier.
I believe outliers is the best answer to this question. The previous answer was average, which is the mean.
A large degree of variation between individual measurements, in terms of the units used.
Nm3 is a common unit used in industry to refer to gas emissions or exchange. It stands for Normal cubic meter. "Normal" is always dependant on the individual circumstances of each gas, pressure, and use. To convert Nm3 to a cubic foot of gas (under standard conditions), multiply by 38.04. Therefore, 1,000 Nm3/day = 1 kNm3/day = 38,040 cf/day.
Standard temperature and pressure (STP) is a temperature 0ºC (32ºF) with the air pressure the same as at sea level.
There are 0.25 moles of argon gas present in 5.6 liters at standard conditions (1 mole of any gas occupies 22.4 liters at standard conditions).
Chlorine is already a gas under standard conditions.
Under standard conditions it is a gas.
No; the ideal gas is theoretical concept.STP is an acronym for standard temperature and pressure; an important conditions for the measurements in similar situations.
We need standard measurements because it helps us to find the measurements of things.
Xenon is a noble gas at room temperature and pressure, meaning it exists as a gas.
nonstandard and standard measurements...

Under standard laboratory conditions, calcium is a solid.
To calculate the volume at standard conditions, we can use the ideal gas law equation, PV = nRT. First, calculate the number of moles of xenon gas using the given conditions. Then, using the molar volume at STP (22.4 L/mol), calculate the volume of xenon gas at standard conditions.
The reference conditions for gas volume are 0oC and 101.325 kPa, corresponding with a molar (ideal) gas volume of 22.414m3 / (kg.mol). This is shown as m3 (normal) or abbreviated to (non-SI) "Nm3".A unit not frequently used are standard cubic metres "sm3"; Conditions at 0oC and 101.325 kPa.
