An element exists in bcc lattice with a cell edge of 288 pm. Calculate its molar density is `7.2g//cm^(3)`

Explanation

To solve the problem, we need to calculate the molar mass of an element that exists in a body-centered cubic (BCC) lattice, given its cell edge and density.

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Cell edge (a) = 288 pm = 288 x 10^-10 cm (since 1 pm = 10^-12 m and 1 cm = 10^-2 m)
- Density (D) = 7.2 g/cm³
- For BCC lattice, the number of atoms per unit cell (Z) = 2
