What will be the molality of the solution containing 18.25 g of HCl gas in 500 g of water ?

Options

A. 0.1 m
B. 1 M
C. 0.5 m
D. 1 m

Explanation

To find the molality of the solution containing 18.25 g of HCl gas in 500 g of water, we will follow these steps:

### Step 1: Convert the mass of the solvent (water) from grams to kilograms.
- Given mass of water = 500 g
- To convert grams to kilograms, divide by 1000:
\[ \text{Mass of water in kg} = \frac{500 \text{ g}}{1000} = 0.5 \text{ kg} \]
