What has the greatest volume at STP?
Five moles of hydrogen gas will occupy the largest volume under standard temperature and pressure.
Which of the following gas samples will have the greatest volume at STP?
So, since STP one mole gives us 22.4 leaders, whichever of these has the greatest amount of moles is going to have us give us the greatest volume. So the one that gives us the greatest volume Is the 10 g of helium.

Which gas will have the highest density at STP?
The highest density among the inert gases is of Neon (Ne). This a factual data. Thus the highest density among given options is of Ne, as all the options are of inert gases.
Which of the following samples of gas would occupy the greatest volume at standard temperature and pressure STP )?
Which of the following samples of gas would occupy the greatest volume at standard temperature and pressure (STP)? Because of the standard molar volume, each of these 1-g samples would occupy the same volume.
Which gas has largest volume?
The gas having the largest volume in the atmosphere ➡️ NITROGEN.
Which gas has the greatest kinetic energy at STP which gas has the greatest kinetic energy at STP h2 o2 AR None of the above all have the same kinetic energy?
Nitrogen and helium, at 100C , have the highest average kinetic energy because they have the highest temperature.

What is the density of co2 g at STP?
Thus, the density of the Carbon Dioxide at S.T.P. (Standard Temperature and Volume) is 1.96 gram/liter.
Which of the following gases has the highest average speed?
1 Answer. Highest speed: Helium at 100°C .
What is the volume of gas at STP?
A PV = nRT problem
So, the volume of an ideal gas is 22.41 L/mol at STP. This, 22.4 L, is probably the most remembered and least useful number in chemistry.
How do you find volume at STP?
It can be written as: V = nRT/P. “P” is pressure, “V” is volume, n is the number of moles of a gas, “R” is the molar gas constant and “T” is temperature.
Which gas has the smallest volume at STP?
Helium, the noble gas with least molar mass will have the smallest density.
Does STP count for sig figs?
Molar volume of gas at STP can be calculated from the ideal gas equation. As of today all numbers in that equation – including R, ideal gas constant – are defined, that is, they have infinite number of significant digits (you can put as many zeros at the end as you need).
What volume will 1.27 moles of helium gas occupy at STP?
Answer. Answer: One mole of a gas occupies 22.4 L at STP. 1.27 mol He x (22.4 L / 1 mol) = 28.4 L.

Do gases behave more like an ideal gas at low pressure or high pressure?
Generally, a gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to intermolecular forces becomes less significant compared with the particles’ kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.
Which is the largest volume?
‘Kiloliter'(Kl) is the largest unit of volume. This being the largest unit, is mainly used to measure the volume of various spaces such as, large…
Which one of the following gases has the largest volume in the atmosphere *?
(Volume in Atmosphere) (a) Nitrogen. (i) 78.08%
Which one of the following gases has the second largest volume in the atmosphere?
Oxygen is the second-largest component of air, constituting almost 21% volume of air.
Which molecules have the highest kinetic energy?
Answer and Explanation: Molecules in the gaseous state have the highest kinetic energy. This is because they are free to move around in random directions.
What has the highest kinetic energy?
Solids have the lowest kinetic energy whereas gases have the highest kinetic energy.
Do all gases have the same kinetic energy at STP?
The average kinetic energy of gas particles is proportional to the absolute temperature of the gas, and all gases at the same temperature have the same average kinetic energy.
What is the volume of N2O formed at STP?
Nitrogen has a molar mass of 14.0067 g/mol and oxygen has a molar mass of 15.999 g/mol. So, N2O has a molar mass of (2*14.0067 + 15.999) g/mol = 44.0124 g/mol. Now, the molar volume of any (ideal) gas at STP is 22.4 L/mol. Thus, the volume of 20.5 g of N2O is (22.4 L/mol) * (20.5 g)/(44.0124 g/mol) = 10.4 L (3 s.f.).
What is STP in chemistry?
Definition. Standard Temperature and Pressure (STP) is defined as 0 degrees Celsius and 1 atmosphere of pressure.
Which of the following conditions is STP?
Key Takeaways: STP or Standard Temperature and Pressure
One common definition of STP is a temperature of 273 K (0° Celsius or 32° Fahrenheit) and the standard pressure of 1 atm. Under these conditions, one mole of a gas occupies 22.4 L.
What gas occupies 22.4 at STP?
One mole of oxygen gas occupies 22.4 l volume at STP.
Which gas particle travels the fastest?
Explanation: The rate of effusion for a gas is inversely proportional to the square-root of its molecular mass (Graham’s Law). The gas with the lowest molecular weight will effuse the fastest. The lightest, and therefore fastest, gas is helium.
