Compute each part of given problem:
Problem: Archimedes principle can be used to calculate the density of a fluid as well as that of a solid. Suppose a chunk of iron with a mass of 408.0 g in air is found to have an apparent mass of 363.5 g when completely submerged in an unknown liquid.
Part I: What mass of fluid does the iron displaces?
Part II: What is the volume of iron?
Part III: Calculate the fluids density.
Please write the step and answer, how you work this problem. Thanks!
