Which of the postulates of dalton's atomic theory explains why we can calculate a theoratical yield for a chemical reaction?

Postulate 4

Explanation:

Dalton's atomic theory-

According to the postulate number four of the  Dalton's atomic theory , the theoretical yield can be calculated for the chemical reaction .

Since ,

A compound is formed by atoms or ions or by elements .

And these atoms combine in a small , simplest , whole number , to form the compound .

And , these numbers of the atoms are always fixed for a particular compound .

Postulate 4 (A compound consists of atoms of two or more elements combined in a small, whole-number ratio. In a given compound, the numbers of atoms of each of its elements are always present in the same ratio).

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

it is b that is the answer.
