Explanation:
A mole is the amount of matter or substance that contains the Avogadro's number of particles.
1 mole of a substance = 6.02 x 10²³ atoms
Now solving:
a:
1.2 x 10² atoms ;
Number of moles = = 2.0 x 10⁻²¹moles
b:
3.87 x 10²¹ molecule:
Number of moles = = 6.4 x 10⁻³moles
c. 4.81 x 10¹⁴ molecules:
Number of moles = = 8.0 x 10⁻¹⁰moles
Number of molecules = number of atoms = formula units
