Question

At constant temperature and pressure, the volume of a gas is directly proportional to its number of moles.

• A. True
• B. False

Answer 1

The correct option is A True

Avogadro's law states that, "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules".

That is: $V\propto n$

At constant temperature and pressure, the volume of a gas is directly proportional to its number of moles.
