Answer:
126.4 g of 
 are required
Explanation:
Balanced reaction: 
According to balanced reaction-
8 moles of 
 are produced from 2 moles of 
So, 8.70 moles of 
 are produced from 
 moles of 
 or 2.175 moles of 
Molar mass of 
 = 58.12 g/mol
So, mass of 
 required = 
 = 126.4 g
Hence 126.4 g of 
 are required
