For the answer to the question above asking, how many moles of glucose (C6H12O6) are in 1.5 liters of a 4.5 M C6H12O6 solution?
The answer to your question is the the third one among the given choices which is 6.8 mol.
moles glucose = 1.5 x 4.5 = 6.8 

Answer: 6.75 moles

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

\(Molarity=\frac{n}{V_s}\)

Given;

Molarity = 4.5 M

n= moles of solute  (glucose) = ?

 \(V_s\) = volume of solution in L = 1.5 L

Putting in the values we get,

\(4.5=\frac{n}{1.5}\)

\(n=6.75moles\)

Thus moles of glucose are 6.75 moles in 1.5 liters of a 4.5 M \(C_6H_{12}O_6\) solution.
