Question

Green plants use light from the Sun to drive photosynthesis. Photosynthesis is a chemical reaction in which water and carbon dioxide chemically react to form the simple sugar glucose and oxygen gas . What mass of simple sugar glucose is produced by the reaction of 9.51 g of carbon dioxide

Answer 1

The mass of sugar glucose is 6.499 g

Step-by-step explanation:

Data given:

mass of CO₂ = 9.51 g

molar weight of CO₂ = 44.01 g/mol

`n_{CO_(2) } =9.51/44.01=0.216mol`

The reaction is:

C₆H₁₂O₆ + 9O₂ = 6CO₂ + 6H₂O

According the reaction:

1 mol of C₆H₁₂O₆ ------------- 6 moles of CO₂

X mol of C₆H₁₂O₆ ------------- 0.216 moles of CO₂

Clearing X:

`Xmoles_{C_(6)H_(12)O_(6) } =(0.216)/(6) =0.036moles`

molar weight of C₆H₁₂O₆ = 180.516 g/mol

The mass of glucose is:

`mass_{C_(6)H_(12)O_(6) } =0.036*180.516=6.499g`
