Mercury: 0.38
Venus: 0.91
Earth: 1.00
Mars: 0.38
Jupiter: 2.34
Saturn: 1.06
Uranus: 0.92
Neptune: 1.19
Pluto: 0.06
Because weight = mass x surface gravity, multiplying your weight on Earth by the numbers above will give you your weight on the surface of each planet.
So I guess it would be somewhere around 34.2 N
