Answer:

6.49g

Explanation:

Let's consider the balanced reaction for photosynthesis.

6 CO₂ + 6 H₂O = C₆H₁₂O₆ + 6 O₂

We can establish the following relations:

1 mole of CO₂ has a mass of 44.01 g (MW 44.01)
The molar ratio of CO₂ to C₆H₁₂O₆ is 6:1.
1 mole of C₆H₁₂O₆ has a mass of 180.16 g/mol.

The mass of glucose produced by the reaction of 9.51 g of carbon dioxide is:

$9.51gCO_2 \times \frac{1molCO_2}{44.01gCO_2} \times \frac{1molGlucose}{6molCO_2} \times \frac{180.16gGlucose}{1molGlucose} = 6.49g Glucose$
