To determine the nature of the unit cell of KBr, we will follow a systematic approach using the given data: density, unit cell length, and atomic masses of potassium (K) and bromine (Br). ### Step-by-Step Solution: 1. **Given Data**: - Density of KBr (d) = 2.73 g/cm³ - Length of the unit cell (a) = 654 pm = 654 × 10⁻¹² m = 6.54 × 10⁻⁸ cm - Atomic mass of K = 39 g/mol ...
