Answer
1g Chlorine atoms and 1g Chlorine molecules have the same amount of atoms.
Work Step by Step
- 1g chlorine atoms $(Cl)$:
Molar mass: 35.5g/mol
So: $1g \times \frac{1 mol}{35.5g} = 0.0282$ moles of chlorine atoms.
Which means: 0.0282 moles of atoms.
- 1g chlorine molecules $(Cl_2)$:
Molar mass: 71 g/mol
So: $1g \times \frac{1mol}{71g} = 0.0141$ moles of chlorine molecules.
- But, each chlorine molecule $(Cl_2)$ has 2 atoms, so:
$n°(atoms) = 0.0141$ $moles$ $ * 2 = 0.0282$ $moles$.
Therefore, they both have the same number of atoms.
