The chemical equation for photosynthesis is as follows:

6 CO_{2 (g)} + 6H₂O _(l) ? C₆H₁₂O_{6 (s)} + 6 O_2(g)

Every year, the mass of carbon dioxide used by this reaction ona small island is 2.85 × 10⁴ kg. What is the annualenthalpy change resulting from photosynthesis on the island?

Compound	?fHo (kJ/mol)
C6H12O6(g)	—1268
O2 (g)	0
CO2 (g)	—393.5
H2O (l)	—285.8
