Answer :
Final answer:
Beaker A has more mass but Beaker B contains more atoms.
Explanation:
In terms of mass, Beaker A has more mass than Beaker B. However, when it comes to the number of atoms, Beaker B contains more atoms than Beaker A.
The mass of an object is a measure of the amount of matter it contains. Beaker A may have more mass if it contains a denser or heavier substance compared to Beaker B.
The number of atoms in a substance is determined by its chemical formula and the number of atoms per molecule. Beaker B may contain more atoms if it contains a substance with a greater number of atoms per molecule compared to Beaker A.
