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]
If 150 cc of gas A contains X molecules, how many molecules of gas B will be present in 75 cc of B?. The gases A and B are under the same conditions of temperature and pressure.
What are the main applications of Avogadro's law?
Differentiate between N2 and 2N.
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."
How dose Avogadro's Law explain Gay-Lussac's Law of combining volumes?
Samples of the gases O2, N2, CO2 and CO under the same conditions of temperature and pressure contain the same number of molecules x. The molecules of oxygen occupy V litres and have a mass of 8 g under the same conditions of temperature and pressure.
What is the volume occupied by:
- x molecules of N2,
- 3x molecules of CO,
- What is the mass of CO2 in grams?
- In answering the above questions, which law have you used?
The gases hydrogen, oxygen, carbon dioxide, sulphur dioxide, and chlorine are arranged in order of their increasing relative molecular masses. Given 8 g of each gas at STP, which gas will contain the least number of molecules and which gas the most?
What is the co-efficient of real expansion?
State the atomicity of Hydrogen.
