2025 Some Basic Concepts of ChemistryDalton's Atomic Theory Easy Question 5 of 49 in Some Basic Concepts of Chemistry

Dalton's Atomic theory could not explain which of the following?

A Law of conservation of mass
B Law of constant proportion
C Law of multiple proportion
D Law of gaseous volume

The answer is D.

Solution

Dalton's atomic theory explained the laws of chemical combination by mass, but failed to explain Gay-Lussac's law of gaseous volumes.

Dalton's atomic theory provided a logical explanation for the law of conservation of mass, law of definite/constant proportions, and law of multiple proportions, but it could not explain Gay-Lussac's law of combining gaseous volumes (which was later explained by Avogadro's hypothesis).
