Inorganic & Physical Chemistry Reasoning Strategy 1. Crystal Structure Questions When given crystal structure data , always COMPUTE don't guess: 1. Calculate unit cell volume for the crystal system: - Cubic: V = a^3 - Tetragonal: V = a^2 c - Orthorhombic: V = a b c - Monoclinic: V = a b c sin(beta) - Triclinic: V = a b c sqrt(1 - cos^2(alpha) - cos^2(beta) - cos^2(gamma) + 2 cos(alpha) cos(beta) cos(gamma)) - Hexagonal: V = a^2 c sqrt(3)/2 2. Verify density : d = (Z M) / (V Na 1e-24) where V in ų, M in g/mol, Na = 6.022e23 3. Preferred : Use tool (via MCP/SDK). Fallback : 4. For batch compar…
