Answer:
will be 90054 J
Explanation:
Number of moles = (mass)/(molar mass)
Molar mass of 
= 134.45 g/mol
So, 1.00 g of = 
of = 0.00744 mol of
0.00744 mol of produces 670 J of heat
So, 1 mol of produces 
of heat or 90054 J of heat
I THINK that that is true. It's just weathering the rock down not change composition. Lemme know if you get it right please! (:
