According to PF rules, you need to show reasonable effort before receiving help. Tell us what you think, how you would approach the problem and what is the role of the "relevant equations" in the solution.

Nevertheless, the answer to the question posed in the title is "Yes, we can solve this problem."

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
