The molality of a solution having 18 g of glucose dissolved in 500 g of water is

Explanation

To calculate the molality of a solution with 18 g of glucose dissolved in 500 g of water, follow these steps:

### Step 1: Identify the formula for molality
Molality (m) is defined as the number of moles of solute per kilogram of solvent. The formula is:
\[ \text{Molality (m)} = \frac{\text{moles of solute}}{\text{mass of solvent in kg}} \]

### Step 2: Calculate the number of moles of glucose
To find the number of moles of glucose, use the formula:
