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]
State Avogadro's Law.
State: Avogadro's law
Define atomicity of a gas.
A vessel contains N molecules of oxygen at a certain temperature and pressure. How many molecules of sulphur dioxide can the vessel accommodate at the same temperature and pressure?
Calculate the mass of 1022 atoms of sulphur.
[Atomic mass: S = 32, C = 12 and O = 16 and Avogadro's number = 6 × 1023]
The gases chlorine, nitrogen, ammonia and sulphur dioxide are collected under the same conditions of temperature and pressure. The following table gives the volumes of gases collected and the number of molecules (x) in 20 litres of nitrogen. You are to complete the table giving the number of molecules in the other gases in terms of x.
| Gas | Volume (in litres) | Number of molecules |
| Chlorine | 10 | x |
| Nitrogen | 20 | |
| Ammonia | 20 | |
| Sulphur dioxide | 5 |
