Calculation of Water Volume in 15% Glucose Solution

In order to calculate the volume of water needed to prepare a 15% glucose solution, we need to consider the mass of glucose and the final volume of the solution.

Given:
- Mass of glucose = 13.5 g
- Percentage of glucose in the solution = 15%
- Mass of the final solution = 13.5 g (glucose) + x (water)

Calculation:
1. Calculate the mass of glucose in the final solution:
Mass of glucose = 15% of total mass
13.5 g = 0.15(13.5 g + x)

2. Solve for x:
13.5 g = 0.15(13.5 g + x)
13.5 g = 2.025 g + 0.15x
0.15x = 13.5 g - 2.025 g
0.15x = 11.475 g
x = 11.475 g / 0.15
x = 76.5 g

Result:
The volume of water needed to prepare a 15% glucose solution by dissolving 13.5 g of glucose is 76.5 g.
