प्रश्न
You have collected
- 2 litres of CO2
- 3 litres of chlorine
- 5 litres of hydrogen
- 4 litres of nitrogen and
- 1 litre of SO2
under similar conditions of temperature and pressure. Which gas sample will have the least number of molecules? Justify your answers.
उत्तर
According to Avogadro's law, equal volumes of gases contain equal no. of molecules under similar conditions of temperature and pressure. This means more volume will contain more molecules and least volume will contain least molecules.
So, 1 litre of SO2 will contain the least number of molecules.
संबंधित प्रश्न
A gas cylinder contains 12 x 1024 molecules of oxygen gas.
If Avogadro’s number is 6 x 1023; Calculate:
1)The mass of oxygen present in the cylinder.
2) The volume of oxygen at S.T.P. present in the cylinder. [O = 16]
Name the law om which same conditions of temperature and pressure
Samples of the gases O2, N2, CO2 and CO under the same conditions of temperature and pressure contain the same number of molecules represented by X. The molecules of Oxygen, occupy V litres and have a mass of 8 g. Under the same conditions of temperature and pressure:
In answering the above questions, which law have you used?
A gas cylinder contains 24 × 1024 molecules of nitrogen gas. If Avogadro's number is 6 × 1023 and the relative atomic mass of nitrogen is 14, calculate the mass of nitrogen gas in the cylinder.
State : Avogadro's law
Explain Why?
"The number of atoms in a certain volume of hydrogen is twice the number of atoms in the same volume of helium at the same temperature and pressure."
What are the main applications of Avogadro's Law?
How dose Avogadro's Law explain Gay-Lussac's Law of combining volumes?
Calculate :
The weight of 1022 atoms of carbon [C = 12, Avogadro’s No. = `6xx10^23 ]`
State the atomicity of Phosphorus.
