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.

What is the density of francium at STP?
The estimated value of the density of francium at STP is 1,87 g/cm3.
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?
no
Which combination of temperature and pressure correctly describes standard temperature and pressure or STP?
The pressure of a has at STP is 1 bar.
What is the significance of STP in relationship to the volume of 1 mole of an ideal gas?
STP = Standard Temperature and Pressure After the IUPAC rules the standard temperature is 0 0C and the standard pressure is 100 kPa (0,986 atm). The molar volume of an ideal gas at STP is 22,710 980(38) L.
What symbol represents a molecule at STP?
the symbol that represent molecule at stp is energy or force
How fast does hydrogen effuse?
Rms= sqrt(((3)(8.314)(273.15k))/(1g/mole)) = 82.54 is the speed of one hydrogen molecule. Assuming stp
Which element has the greatest density at STP?
i dont now
What is the speed of sound in stp?
343 m/s
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
How many grams of oxygen gas is contained in 11.2L 02 gas at stp?
To determine how many atoms are present in 56 liters of oxygen gas at STP you first need to know that there are two atoms in a single molecule. Then, you would work the scientific formula to determine the number of molecules in the oxygen gas.
One centimeter cube of methane at STP will have how much molecules?
the answer is 8.45 molecules. Yay a 45th molecule. Weird huh.
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.
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.
How many grams of carbon dioxide will occupy a volume 500.0 ml at STP?
We know that one mole of any gas at STP occupies 22.4 liters of volume. We also know that one mole of carbon dioxide is 44.01 grams of CO2. If there are 44.01 grams of this gas in 22.4 liters at STP, then there will be about 0.98 grams of CO2 in half a liter (500 ml) of the gas at STP.
Why is it important to know the mass and volume of gas at STP?
To find it's density
