question_answer 73)

  In photosynthesis, 6 molecules of carbon dioxide combine with an equal number of water molecules through a complex series of reactions to give a molecule of glucose having a molecular formula . How many grams of water would be required to produce 18 g of glucose? Compute the volume of water so consumed assuming the density of water to be .  

Answer:

  During photosynthesis, following reaction takes place Molecular formula of glucose 180 g of glucose require the amount of water = 108 g 18 g of glucose will require the amount of water  As the amount of water consumed (m) = 10.8 g Given that,       density (d) of water Volume (V) of water consumed
