An element crystallises in bcc lattice with cell edge of `3 xx 10^(-8) cm`. The density of the element is `6.89 g cm^(-3)` . Calculate the molar mass of the element.

Explanation

To calculate the molar mass of an element that crystallizes in a body-centered cubic (BCC) lattice, we can use the formula for density. The density (d) is given by the formula:

\[ d = \frac{Z \cdot M}{A^3 \cdot N_0} \]

Where:
- \( Z \) = number of atoms per unit cell
