Calculate
(i) the volume of one molecule of water.
(ii) the radius of a water molecule assuming the molecule to be spherical.
(Given that the density of water is `1 g/cm^3`.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Calculate the volume of one molecule of water

1. **Identify the molar mass of water (H₂O)**:
- The molar mass of water is 18 g/mol.

2. **Use Avogadro's number**:
...
