Air is a mixture of different gases (nitrogen, oxygen, water vapor, argon, carbon dioxide, etc.) but all are gases, so air is fully 'gaseous'.
- if the cylinder is sealed by welding, the same volume- if the cylinder is open - any initial gas
The volume of gases in 100 cm3 of air depends on the composition of the air. Typically, air is approximately 78% nitrogen, 21% oxygen, and 1% other gases. Each gas will occupy a volume proportional to its mole fraction. Given the molecular weights of nitrogen (28 g/mol) and oxygen (32 g/mol), you can calculate the volumes using the ideal gas law.
Nitrogen, N2, (about 79% in air) is a rather inert gas.
The decrease in volume of air is due to the copper powder absorbing oxygen from the air during the process, forming copper oxide. This chemical reaction reduces the amount of gas present in the container when it is cooled back to room temperature.
This depends on the nature of this solid, temperature, pressure, stirring, particles dimension etc.
Its 100cm3 , or 100ml, or 10-4 m3

No, 100cm3 is only 0.026 gallon.
The weight of an empty 100cm3 evaporating basin would depend on the material it is made from. However, a common material like borosilicate glass typically weighs around 100-150 grams.
1 gallon has more volume. 100cm3 is basically 1/10th of a liter which is 1,000cm3
What is the volume of 35.7g of sodium chloride in 100cm3 of cold water?

No.
Nitrogen, N2, (about 79% in air) is a rather inert gas.
you divide by 1000 to convert from cm3 to dm3, so 100cm3 is 0.1dm3
The decrease in volume of air is due to the copper powder absorbing oxygen from the air during the process, forming copper oxide. This chemical reaction reduces the amount of gas present in the container when it is cooled back to room temperature.
Technically, air is a gas. It is a mixture of nitrogen and oxygen with traces of many other gasses.
