I multiplied the number of moles by the molar mass

(4.87 x 10^25 atoms ) / (6.02 x 10^23 atoms ) = 80.897 moles

I divided by (6.02 x 10^23) atoms because that is the Avogadro Number that tells you how many atoms there are in a mole of any element.

5289.04g x kg/1000g = 5.289kg = 5.29kg

I multiplied the number of moles by the molar mass
