Temperature measures kinetic energy on a molecular level, and kinetic energy depends upon two things, speed and mass. So, if the temperature is a constant (since you have specified STP) the lighter the molecule is, the faster it will be moving. The lightest molecule, of course, is hydrogen. So hydrogen moves the fastest of any molecule at a given temperature.

Density of natural gas at STP?
STP stands for Standard Temperature and Pressure. At STP, the pressure of natural gas is 1 atm, and 1 mole of gas takes up 22.4 liters.
What is Neon's density at STP?
Neon's density at standard temperature and pressure (STP) is approximately 0.9 grams per liter.
What is the physical state at STP of beryllium?
Beryllium is a solid metal at room temperature.
What does a molar volume of a gas at STP occupy?
At STP (standard temperature and pressure), one mole of any gas occupies a volume of 22.4 liters. This is known as the molar volume of a gas at STP.
What is the density of francium at STP?
The density of francium at standard temperature and pressure (STP) is approximately 1.87 grams per cubic centimeter. Francium is a highly radioactive element and is rare in nature, so its properties are mainly theoretical.
What symbol represents a molecule at STP?
The symbol "STP" stands for Standard Temperature and Pressure, which is defined as 0 degrees Celsius and 1 atmosphere pressure. There is no specific symbol that represents a molecule at STP, as STP is a set of specific conditions used for comparing and measuring properties of gases.
Which element has the greatest density at STP?

How much space does one molecule of gass occupie in STP?
In 22.4 litres there are Avogadro's number of molecules. Divide one by the other to get liters per molecule.
What is the speed of STP cable?
10 to 1000 Mbps for less than +/- 100m
What is the speed of sound in stp?
The speed of sound in standard temperature and pressure (STP) conditions is approximately 343 meters per second (m/s) in dry air at 20 degrees Celsius.
In a sample of oxygen gas at stp which represents the greatest number of molecules?
The gas sample that has the greatest number of molecules is the one with the largest amount of substance, which is measured in moles. At STP (standard temperature and pressure), one mole of any gas occupies a volume of 22.4 liters. Therefore, the gas sample with the largest volume at STP will have the greatest number of molecules.
What is the most useful thing to know about gases in STP?
Any gas at STP is 0 degrees Celsius and 1 ATM when at 22.414L.
What would be the volume of 6.00 g of helium gas at STP?
If these atoms are loose unities, not bonded in a molecule, it would be about 22 dm3 at 0oC and standard pressure (STP). If the atoms would have formed gas molecules, e.g. CO2 or SF6, the answer would be different, because 6.02 x 1023 molecules always take in a volume of about 22 dm3 at STP. But with CO2 you would have then 18 x 1023 atoms because there are 3 atoms in one molecule.
Which 1.0 liter sample has the greatest mass at STP a CH4g b CL2g c CO2g d H2g?
The sample with the greatest mass at STP would be the one with the highest molar mass, as 1 mole of any substance at STP occupies the same volume (22.4 L). Among the given options, the sample with Cl2 gas (molar mass = 70.9 g/mol) would have the greatest mass.
What will be the volume occupied by one molecule of water at stp?
At STP, water is a liquid with a density of 1000.000 grams per liter. The gram molecular mass of water is 18.01528. Therefore, the number of moles of water in one liter is 1000.000/18.01528 or 55.5084 moles. The number of molecules in one liter is therefore 55.5084 X 6.022 X 1023 or about 3.34272 X 1025, and the volume of one molecule is therefore 1 [exact]/3.34272 X 1025 or 2.99158 X 10-24 liter.

What is gold's phase at STP?
Gold is a solid at standard temperature and pressure (STP).
