What is the density of H2S gas at STP?
The density of hydrogen sulfide is 1.363 g/cm3.
Why is nitrogen gas at STP less dense than Xe gas at STP?
Nitrogen gas at STP is less dense than xenon gas at STP because nitrogen has a lower atomic mass and thus lighter molecules, leading to lower density. Additionally, xenon is a noble gas with a higher atomic mass and larger atomic radius, contributing to its higher density.
What is the mass of 43.7 L of helium at STP?
The mass of 43,7 L of helium at STP is 7.8 g.
Which group 15 element exists as diatomic molecules at STP?
Nitrogen (N2) is the Group 15 element that exists as diatomic molecules at standard temperature and pressure (STP).
What sample at STP has the same number of molecules as 5 liters of NO2 at STP?
At STP, 1 mole of any ideal gas occupies 22.4 liters. Therefore, 5 liters of NO2 at STP will represent 0.22 moles (5/22.4), and this is the case for any other ideal gas. So, the answer is that 5 liter of ANY ideal gas will have the same number of molecules as 5 liters of NO2.
What is the density at STP of hydrogen sulfide gas (H2S)in grams per liter?
The density of hydrogen sulfide gas (H2S) at standard temperature and pressure (STP) is approximately 1.363 grams per liter. This value can be derived from the molar mass of H2S, which is about 34.08 g/mol, and the fact that one mole of gas occupies 22.4 liters at STP. Thus, the density is calculated as the molar mass divided by the molar volume.

What is the density at STP of (H2S) in grams per liter?
At standard temperature and pressure (STP), the density of hydrogen sulfide (H₂S) is approximately 1.363 grams per liter. This value can be calculated using the molar mass of H₂S, which is about 34.08 g/mol, and the ideal gas law, considering that one mole of gas occupies 22.414 liters at STP. Therefore, the density is derived by dividing the molar mass by the volume at STP.
How do you know which molecule has the greatest speed at STP?
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.
A chemical reaction produces 0.884 mol of H2S gas What volume will that gas occupy at STP?
The volume is 22,1 L.

What is the average distance between oxygen molecules at Standard Temperature and Pressure (STP)?
The average distance between oxygen molecules at Standard Temperature and Pressure (STP) is approximately 3.3 nanometers.
