You can put this solution on YOUR website!
given:
mass is m=+68kg
formula of weight: W=g%2Am
on the earth:
W=9.8%2A68+=+666.4+=+6.7%2A10%5E2newton
on the moon:
W=1.7%2A68+=+115.6+=1.6%2A10%5E2 newton

in outer space:
In outer space with no gravity there is no weight and the answer is 0+newton.
The key is constant velocity which means zero acceleration due to gravity.
