Which postulate of Dalton’s atomic theory can explain the law of definite proportions?

Dalton’s Atomic Theory and Law of Definite Proportions:

– Dalton’s Postulate:
– Law of Multiple Proportions (or Postulate of Indivisibility): States that elements are composed of indivisible particles called atoms, which combine to form compounds in simple, whole number ratios.

– Explanation of Law of Definite Proportions:
– Law of Definite Proportions: Asserts that a compound always contains the same elements in fixed proportions by mass, regardless of the compound’s source.

– Connection:
– Dalton’s idea of atoms combining in specific, simple ratios directly elucidates the Law of Definite Proportions.

– Elucidation:
– The fixed ratios in which atoms of different elements combine form the basis for the consistent proportions observed in compounds.

– **Conclusion:**
– The Law of Definite Proportions is inherently explained by Dalton’s postulate that atoms combine in uncomplicated ratios, providing a foundational understanding of how elements come together to form compounds with consistent mass ratios.
