Glucose (dextrose) solutions are given intravenously to patients combined with other drugs. Different concentrations of glucose are used for different purposes. A 5% (w/w) glucose solution is commonly used. The density of this solution is 1.02 g `mL^(-1)`.
What is the mole fraction of glucose in the solution?

Explanation

To find the mole fraction of glucose in a 5% (w/w) glucose solution, we can follow these steps:

### Step 1: Understand the composition of the solution
A 5% (w/w) glucose solution means that there are 5 grams of glucose in every 100 grams of the solution. Therefore, in 100 g of the solution:
- Mass of glucose = 5 g
- Mass of water = 100 g - 5 g = 95 g

### Step 2: Calculate the number of moles of glucose
