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 of water? Be sure your answer has the correct number of significant digits.

Answer 1

Mass of glucose = 180.156 g

Step-by-step explanation:

Chemical equation:

6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂

Number of moles of water = 6 mole

Molar ratio:

Mole ratio of water and glucose:

H₂O : C₆H₁₂O₆

6 : 1

Mass of glucose produced by 6 mole of water:

Mass of glucose = number of moles × molar mass

Mass of glucose = 1 mol × 180.156 g/mol

Mass of glucose = 180.156 g
