Answer:

8239.2g

Explanation:

Given parameters:

Number of atoms in Br  = 6.2 x 10²⁵atoms

Unknown:

Mass of Br = ?

Solution:

From mole concepts, we know that:

       1 mole of a substance contains 6.02 x 10²³ atoms/mol

 Molar mass of Br  = 80g/mol

6.2 x 10²⁵atoms  x [tex]\frac{1}{6.02 x 10^{23} }[/tex] [tex]\frac{mol}{atoms}[/tex] x  80 x [tex]\frac{g}{moles}[/tex]  

          = 8239.2g
