Answer: 6.75 moles
Step-by-step explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
Given;
Molarity = 4.5 M
n= moles of solute (glucose) = ?
= volume of solution in L = 1.5 L
Putting in the values we get,

Thus moles of glucose are 6.75 moles in 1.5 liters of a 4.5 M
solution.
