Answer: 125 g
Explanation:
To calculate the moles :

The balanced reaction is:
According to stoichiometry :
1 mole of
require = 3 moles of 
Thus 1.30 moles of
will require=
of 
Mass of 
Thus 125 g of
will be needed to burn 36.1 g of 
In the column have the same electrons on the outer shell. Which the outer shell electrons are call valence electrons.
Answer:
262.821 g/mol is the molar mass of Beryllium diiodide.
