I have a couple of questions on archimedes' principle

[Lexi2009]

the question is:
consider that a balloon filled with 1 liter of water (1000 cm^3) in equilibrium in a container of water,
what is the mass of the liter of water?
what is the weight of the 1 liter of water?
what is the weight of water displaced by the balloon ?
what is the buoyant force on the balloon?

Are there any equations i can use for these four questions. i really don't understand how to do this without any equations...

Thank you!

Welcome to PF.

There is w = m*g

Then there's Archimedes' principle.

So how much water is displaced by 1 liter of water?

Thank you. so here is what i came up with...
a. 1000 g
b. 9,800 N
c. 9,800 N
d. 9,800 N

Any make sense?
