Question
The radius of gyration (Rg) is directly proportional to the molecular weight Ma, where ‘a’ is a constant. The value of ‘a’ for a spherical molecule is
Solution
The value of 'a' for a spherical molecule is 1/3. This is because the radius of gyration for a spherical molecule is proportional to the cube root of the molecular weight. Therefore, in the equation Rg ∝ Ma, 'a' would be 1/3.
