Green plants use light from the Sun to drive photosynthesis, a chemical reaction in which liquid water and carbon dioxide gas form aqueous glucose C6H12O6 and oxygen O2 gas. Calculate the moles of water needed to produce 0.075mol of glucose. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits

Respuesta :

Answer: 0.45 moles of water are needed to produce 0.075mol of glucose.

Explanation:

The balanced chemical reaction is:

[tex]6CO_2(g)+6H_2O(l)\rightarrow C_6H_{12}O_6(aq)+6O_2(g)[/tex]

According to stoichiometry :

1 mole of glucose require = 6 moles of [tex]H_2O[/tex]

Thus 0.075 moles of glucose require = [tex]\frac{6}{1}\times 0.075=0.45[/tex] moles of [tex]H_2O[/tex]

0.45 moles of water are needed to produce 0.075mol of glucose.
