Chromium crystallises in bcc structure .If its edge length is 300 p m , find its density .Atomic mass of chromium is 52u .`[N_A=6.022 xx 10^(23) cm ,M = 52 _u `

Explanation

To find the density of chromium, which crystallizes in a body-centered cubic (BCC) structure, we can follow these steps:

### Step 1: Identify the parameters
- Atomic mass of chromium (M) = 52 u
- Edge length of the BCC unit cell (a) = 300 pm = 300 x 10^-10 cm
- Avogadro's number (N_A) = 6.022 x 10^23 atoms/mol
- Number of atoms per unit cell in BCC structure (Z) = 2
