At `100^oC` and 1 atm, if the density of the liquid water is `1.0gcm^(−3)` and that of water vapour is `0.0006gcm^(−3)`, then the volume occupied by water molecules in 1 L of steam at this temperature is :

Explanation

To solve the problem of finding the volume occupied by water molecules in 1 L of steam at 100°C and 1 atm, we can follow these steps:

### Step 1: Understand the Given Data
- Temperature (T) = 100°C = 373 K (since K = °C + 273)
- Pressure (P) = 1 atm
- Density of water vapor = 0.0006 g/cm³
- Volume of steam = 1 L = 1000 cm³
