If your friend can lift a 31kg block, how much force would that require on Earth?

That's correct...so at most, your friend can provide a force of 303.8N. Now note that the acceleration due to gravity on Mars (which you can calculate using Newton's Law of Universal Gravitation) is about 3.7m/s^2. \[F=ma=303.8N=x(3.7m/s^2)\]Solve for x and you'll know how many kg your friend will be able to lift on Mercury.

And although @Shane_B said "Mars" once, Shane_B meant Mercury, and 3.7 m/s^2 is close :)

Oops, yes, Mercury :)
