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
