**Step-by-Step Text Solution:** 1. **Understanding Dalton's Atomic Theory**: John Dalton proposed a theory in the early 19th century that laid the foundation for modern chemistry. His theory consists of several postulates that describe the nature of atoms and their interactions. 2. **Law of Conservation of Mass**: This law, formulated by Antoine Lavoisier, states that mass is neither created nor destroyed in a chemical reaction. This means that the total mass of reactants before a reaction must equal the total mass of products after the reaction. 3. **Connecting the Two Concepts**: Dalton's atomic theory includes a postulate that reflects the law of conservation of mass. This postulate states that "atoms cannot be created nor destroyed in a chemical reaction." This means that during a chemical reaction, the atoms present in the reactants are rearranged to form products, but the total number of atoms remains constant. ...
