Answer:
Because the Calvin cycle is dependent on the the product from light reaction.
Explanation:
The Calvin cycle is the light independent phase of photosynthesis during which carbon is fixed. This step requires energy generated during the light dependent phase of the photosynthesis.
Hence, if the light dependent reaction does not occur, the required energy to drive carbon fixation will be lacking and the Calvin cycle will not be able to proceed.
The given question is incomplete. The complete question is:
Calculate the number of moles and the mass of the solute in each of the following solution: 100.0 mL of 3.8 × 10−5 M NaCN, the minimum lethal concentration of sodium cyanide in blood serum
Answer: The number of moles and the mass of the solute are
and
respectively
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

where,
n = moles of solute
= volume of solution in ml


n = moles of
= 


Thus the number of moles and the mass of the solute are
and
respectively
75 g of sodium hydroxide is present in the solution.
<u>
</u><u>Explanation</u><u>
:</u>
Given
:
Molarity of sodium hydroxide solution= 2.5 M
Litres of Solution = 750 mL
Molar mass of NaOH = 40 g/mol
To Find:
Grams of Sodium Hydroxide =?
Solution
:
Molarity of the solution is expressed in Litres, So Converting 750.0 mL to Litres we have
750.0mL=0.750 Litres
Grams of Solution
, moles= 
Where
M = Molarity
L = litres of solution
mol= moles of solute

Mol = 1.875
Also the molecular weight of NaOH is 40.00 g/mol
Grams of sodium hydroxide = 1.875 mol * 40.00 g/mol = 75 g
