The dimensions of the unit cell of crystalline lysozyme are a = 79.1 Å, b = 79.1 Å, and 37.9 Å. The

The dimensions of the unit cell of crystalline lysozyme are a = 79.1 Å, b = 79.1 Å, and 37.9 Å. The

interaxial angles are all 90°. Each unit cell contains eight lysozyme molecules. The density of crystalline lysozyme is 1.242 g/cm3, and chemical analysis shows that 64.4 % (by weight) is lysozyme, the rest being water and salt. From these data, calculate the molecular weight of lysozyme.
