Question

A metal has bcc structure and the edge length of its unit cell is 3.04 Å. The volume of the unit cell in cm³ will be?

• A. \( 1.6 \times 10^{-21} \, \text{cm}^3 \)
• B. \( 2.81 \times 10^{-23} \, \text{cm}^3 \)
• C. \( 6.02 \times 10^{-23} \, \text{cm}^3 \)
• D. \( 6.6 \times 10^{-24} \, \text{cm}^3 \)

Hint:

For a cubic unit cell, the volume is simply the cube of the edge length.

Answer 1

The Correct Option is B

The volume of the unit cell can be calculated using the formula \( V = a^3 \), where \( a \) is the edge length of the unit cell. After converting the edge length to cm, the volume can be calculated.
