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]
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.
Solve the following:
A vessel contains X number of molecules of hydrogen gas at a certain temperature and pressure. How many molecules of nitrogen gas would be present in the same vessel under the same conditions of temperature and pressure?
State : 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."
Define or explain the term
