Question 12 of 25 Which of the following is the best summary of Avogadro's law?
A. Equal amounts of all gases occupy 22.4 L at all conditions.
B. Equal amounts of all gases have the same volume at the same
conditions,
C. Every gas has a different volume at STP.
D. The volume a gas occupies depends on gas type.
SUBMIT

B. Equal amounts of all gases have the same volume at the same

conditions

Explanation:

Amedo Avogadro found the relationship between volume of a gas and the number of molecules contained in the volume.

The law states that "equal volumes of all gases at the same temperature and pressure contains equal number of molecules or moles".

The law describes the behavior of gases when involve in chemical reactions. It enables one to change over at will in any statement about gases from volumes to molecules and vice versa.

So, the right option is B which implies that equal amounts of all gases have the same volume at the same conditions.
