Question
Which application determines Avogadro’s las?
- Atomicity of gases
- The molecular weight of gas
- The gram molar mass of gas
- The formula mass of gas
Hint:
Avogadro's law or Avogadro-Ampère's hypothesis is an experimental gas law relating the volume of a gas to the amount of substance of gas present.
The correct answer is: The molecular weight of gas
Avogadro's law or Avogadro-Ampère's hypothesis is an experimental gas law relating the volume of a gas to the amount of substance of gas present. The law is a specific case of the ideal gas law.
It states that the total number of molecules or atoms of a gas is directly proportional to the volume that the gas occupies at a constant temperature and pressure.
The molecular weight of gas determines Avogadro's law.
