The angular velocity is defined as "the angle changing over time."

From the given of the problem:

m = 100g
rate of revolution = 50 rev / min

Therefore, using the formula:

angular velocity = rate of revolution x 2*pi / revolution

Substituting:

angular velocity = (50 revs / min) x ( 2*pi radians / rev ) = 100*pi radians / min

As you can see, mass is not a part of the equation for solving the angular velocity therefore the amount of mass does not affect its value.
