Consider again the reaction for photosynthesis: 6co2 + 6h2o → c6h12o6 + 6o2. select the correct mole ratio to complete the calculation shown below.

Since the calculation you want to complete is missing, I can help you by telling you the different mole ratios that you can derive from the chemical equation.

1) Balanced chemical equation (given):

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

2) Mole ratios are give by the coefficients of the balanced chemical equation

6 CO₂ : 6 H₂O : 1 C₆H₁₂O₆ : 6 O₂

3) So, these are some of the mole ratios:

a) mole ratio CO₂ to H₂O = 6:6 = 1:1

b) mole ratio CO₂ to C₆H₁₂O₆ = 6:1

c) mole ratio CO₂ to O₂ = 6:6 = 1:1

d) mole ratio H₂O to O₂ = 6:6 = 1:1

As you see, you can calculate the mole ratio of any two compounds of the formula from the coefficients in the balanced chemical equation.
