If there is an object on earth with a mass of 12.0kg, it would weigh 12.0kg * 9.81m/s^2 which would be 117N. Is this correct?

Yes. Weight is the result of the force of gravity on earth your object weighs 117N. On the moon something else and on Mars something else. But its mass is the same everywhere (essentially).

It will exert a force of 117N on whatever supports it. But, in common usage, we'd say that it weighs 12 kilos. We're just accustomed to operating in a (more or less) standard 1g accelleration field so we tend to equate 'mass' with 'weight' ☺

Yes. The unit of mass is kg, and the unit of weight is Newton, the same as force. Using Newton's equation, Force = Mass x Acceleration, thinking that weight is a kind of force, you get the weight by multiplying the mass by the earth's gravitational acceleration.
