Answer:
687.5 g of CO2
Explanation:
We'll begin by writing the balanced equation for photosynthesis. This is illustrated below:
6CO2 + 6H2O —> C6H12O6 + 6O2
Next, we shall determine the mass of CO2 absorbed and the mass of O2 released from the balanced equation. This is illustrated below:
Mass of CO2 = 12 + (2 × 16) = 12 + 32
= 44 g/mol
Mass of CO2 from the balanced equation = 6 × 44 = 264 g
Molar mass of O2 = 2 × 16 = 32 g/mol
Mass of O2 from the balanced equation = 6 × 32 = 192 g
Summary:
From the balanced equation above,
264 g of CO2 were absorbed to release 192 g of O2.
Finally, we shall determine the mass of CO2 absorbed to release 500 g of O2. This can be obtained as follow:
From the balanced equation above,
264 g of CO2 were absorbed to release 192 g of O2.
Therefore, Xg of CO2 will be absorbed to release 500 g of O2 i.e
Xg of CO2 = (264 × 500)/192
Xg of CO2 = 687.5 g
Thus, 687.5 g of CO2 will be absorbed to release 500 g of O2.
