In a crystal lattice of a compound, each corner of a cube is joined by sodium, each edge of a cube has oxygen and centre of a cube is joined by tungsten (W), then give its formula :

Options

A. `Na_(2)WO_(4)`
B. `NaWO_(3)`
C. `Na_(2)WO_(2)`
D. `Na_(2)WO_(3)`

Explanation

To determine the formula of the compound based on the arrangement of sodium, oxygen, and tungsten in a cubic crystal lattice, we can follow these steps:

### Step 1: Identify the positions of the atoms in the cubic lattice.
- Sodium (Na) is located at the corners of the cube.
- Oxygen (O) is located at the edges of the cube.
- Tungsten (W) is located at the center of the cube.

### Step 2: Calculate the contribution of sodium atoms.
