<span>The question is asking for the number of valence electron that are available fo bonding in bromine. Bromine belongs the group 7 of the periodic table, thus it has seven electrons in its outermost shell.

Answer:
37.1 g of Arsenic
Explanation:
2.98 x 10^21 atoms of Arsenic x 74.92g/6.02 x 10^23
= 223.26 x 10^21/6.02 x 10^23
= 2.2326 x 10^23/6.02 x 10^23
= 37.1 g of Arsenic
