Problem E15A.4(b)

An orthorhombic unit cell has dimensions a = 769pm, b = 891pm, and c = 690pm. Calculate the spacing, d, of the {312} planes.

Step-by-Step Solution:
Step 1 of 3

Solutions - Solute and solvent mol solute - Molality​ (​m)= kg solvent - At a lower concentration, molality=molarity - The measure of intensity is directionally proportional to fractional division - Freezing point depression - Boiling point elevation - T b = T + △T b - T f = T −f△T - △T = imK - Vant Hoff factor : ​i - Used to represent moles of substances that dissolve/break up - If substance doesn’t break up, ​i=1 - Π = MRT → Osmotic pressure - P = χ P* ° - P= measured vapor pressure; χ= mole fraction; P = vapor of pure solvent °
