State Avogadro's Law.
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?
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?
A gas cylinder contain 12 × 1024 molecules of oxygen gas
If Avogadro's number is 6 × 1023,
calculate :
(i) The mass of oxygen present in the cylinder.
(ii) The volume of oxygen at STP present in the Cylinder[O=16]
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 |
Calculate :
The weight of 1022 atoms of carbon [C = 12, Avogadro’s No. = `6xx10^23 ]`
