The lattice constant 'a' for a cubic crystal is given by a = √3 × 3.7 / √3 Å. Calculate the value of 'a'.

1. 4.3 Å
2. 5.0 Å
3. 3.7 Å
4. None of the above

Correct answer: 3.7 Å

Solution

The given expression simplifies as follows: a = (√3 × 3.7) / √3 = 3.7 Å. Hence, the correct value of 'a' is 3.7 Å.
