Question

How does mass affect angular acceleration?

Answer 1

angular acceleration is independent of mass of the body

as

ang acc=dw/dt

w=angular velocity

Answer 2

When a torque is applied to an object it begins to rotate with an acceleration inversely proportional to its moment of inertia. This relation can be thought of as Newton's Second Law for rotation. The moment of inertia is the rotational mass and the torque is rotational force. Angular motion obeys Newton's First Law.
