Answer:3 moles
Explanation:
For every three molecules of CO2 that enters the Calvin cycle, one molecule of the three carbon glyceraldehyde 3-phosphate (G3P) is produced. Two molecules of G-3-P are required to produce one molecule of glucose. Therefore, the Calvin cycle needs to make a total of 6 turns to produce two molecules of G-3-P.

Hope this answer can help you. Have a nice day!
The Molarity of the solution is given by:
--- (A)
But NaCl, which is a solute, is given in grams.
Therefore, first, we need to convert grams into moles.
Molecular weight of NaCl = 58.44 grams/mole.
So,
117 grams * (moles/ 58.44 grams) = 2.00 moles of NaCl
Now that we have moles of NaCl, plug in the values in (A):
(A) => Molarity = (2 / 2.7 ) = 0.741 moles/litre
The correct answer is: 0.741 moles/litre = Molarity
