Answer is: maximum amount of oxygen is 17,6 g.

Chemical reaction: 4C₃H₅N₃O₉ → 6N₂ + 12CO₂ + 10H₂O + O₂.

m (C₃H₅N₃O₉) = 5,00·10² g = 500 g.

n (C₃H₅N₃O₉) = m (C₃H₅N₃O₉) : M (C₃H₅N₃O₉).

n (C₃H₅N₃O₉) = 500 g : 227,09 g/mol.

n (C₃H₅N₃O₉) = 2,2 mol.

From chemical reaction: n (C₃H₅N₃O₉) : n (O₂) = 4 : 1.

n (O₂) = 2,2 mol : 4.

n (O₂) = 0,55 mol.

m (O₂) = n (O₂) · M (O₂).

m (O₂) = 0,55 mol · 32 g/mol.

m (O₂) = 17,6 g.
