Final answer:
Your weight on Mercury would be less than 115 lbs compared to your weight on Venus, due to Mercury's smaller mass and radius.
Step-by-step explanation:
Your weight on a planet depends on the planet's mass and radius, as well as the force of gravity on that planet. Since Mercury is smaller than Venus, it has less mass and a smaller radius, resulting in a weaker gravitational force. Therefore, if you weigh 115 lbs on Venus, you would weigh less on Mercury.
To calculate your weight on Mercury, you would need to know the mass and radius of Mercury. Mercury's mass is one-eighteenth that of Earth, and its radius is less than half that of Earth. Using Newton's law of gravity, you can calculate the force of gravity on Mercury and then convert it to weight using your mass. However, without that information, it is not possible to give an exact weight.
