Calculating work not given acceleration, work done by gravity

1. The problem statement, all variables and given/known data
A rope lifts a mass of 20kg vertically 80cm.

How much work is done by the rope on the mass?

How much work is done by gravity on the mass?

2. Relevant equations
W = FΔd
Eg = mgh

3. The attempt at a solution
How much work is done by the rope on the mass?
W = FΔd
W = F(0.8)

This is as far as I’ve gotten. I don’t think this is the correct solution. For this to work, I would need to put the applied force of the rope. The problem is that I don’t know the acceleration of the rope, so I’m thinking this may be the completely wrong approach.

How much work is done by gravity on the mass?
So far what I have is:
W = FΔd
W = mgΔd
W = (20)(9.81)(0)
W = 0

Because gravity doesn’t move the mass, the work done by gravity is zero. I believe this is the correct solution.
