Answer : The mass of [tex]O_2[/tex] produced by photosynthesis is [tex]2.77\times 10^3g[/tex]
Explanation :
The given chemical reaction is:
[tex]6CO_2(g)+6H_2O(l)\rightarrow C_6H_{12}O_6(s)+6O_2(g)[/tex]
From the balanced chemical reaction we conclude that,
As, 2803 kJ of heat produced from 6 moles of [tex]O_2[/tex]
Or, 2803 kJ of heat produced from [tex]6\times 32=192g[/tex] of [tex]O_2[/tex]
So, 40400 kJ of heat produced from [tex]\frac{40400}{2803}\times 192=2767.32g=2.77\times 10^3g[/tex] of [tex]O_2[/tex]
Therefore, the mass of [tex]O_2[/tex] produced by photosynthesis is [tex]2.77\times 10^3g[/tex]
