A molecule with the molecular formula C11H12N2O2 (relative molecular mass = 204.23) crystallized to form monoclinic crystals with a=18.899 Å, b=5.7445 Å, and c=9.309 Å, with β=101.776˚. The crystal density is 1.371 g/cm3. Calculate the unit cell volume. Deduce the number of molecules per unit cell (expected values are between 2 and 8). Show your work/logic.
