## Answer :

**Explanation:**

__To calculate the percentage of the solution, we need to know the mass of the solute (glucose) and the volume of the solution.__

__In this case, we have 5g of glucose dissolved in 100 cm³ of solution.__

__To determine the percentage, we need to compare the mass of the solute (glucose) to the volume of the solution.__

__Since we have the mass of the solute (glucose) and the volume of the solution, we can conclude that the correct answer is:__

__d) 5% w/w (weight/weight)__

__This means that the percentage of the solution is 5% by weight.__
