The concept of weight is inextricably linked to the concept of gravity, so it is a logical contradiction to ask the question. However, the concept of mass could be said, in a way, to refer to the "weight" of an object in the absence of gravitational forces.
Mass refers to the quantity of matter present, and is expressed in terms of how much the object would weigh on Earth. A bit complex, so consider this example: a Bowling ball that weighs 10kg on Earth has a mass of 10kg. On Jupiter the bowling ball would weigh quite a bit more, but its mass would still be 10kg.
The technically correct wording for your question is "What is the mass of the earth?" The answer, based on a quick Google search, is 5.9742 × 1024 kg. That's 5,974,200,000,000,000,000,000,000kg, or if you like fancy-sounding words, it's five septillion, 974 sextillion, 200 quintillion kilograms.
You would weigh 102 lb.

It would weigh 10kg.
If you weighed 196 lbs on Earth, you would weigh 177.7 lbs in Venus.
