How many molecules are in a tablet weighing 500 mg?
Molecules are small particles of a substance made from two or more atoms. If the atoms come from different elements, the molecule will be called a compound. Molecules can have as few as two atoms or hundreds of atoms.
Answer and Explanation:
There is no way to know how many molecules are in a tablet weighing 500 mg without knowing the molecules in the table. Each molecule has a different mass that will determine how many molecules are required to reach the set mass of the tablet.
Even without knowing the molecule's mass, knowing the name of the molecule will identify the atoms that compose the compound. If we know the type and number of atoms in the molecule, we can use the atomic mass of the atoms to determine the mass of the molecule.
In summary, there is not enough information in the question to provide an answer.
