This question is also confusing me…
The density of diamond is 3.51 g/cm^3 and the density of platinum is 21.43g/cm^3. If equal masses of diamond and platinum are transferred to equal volumes of water in separate graduated cylinders, which graduated cylinder would have the greatest volume change? Explain or show with a sample calculation.
Thank you so much…last question promise!

The problem says equal masses so make up a number, say 10 grams.
Then mass = volume x density or
v = mass/density. Using the 10 g and density of each, calculate volume of each.
That will be the volume occupied by the 10 g sample of each. The largest volume will displace the most water from a graduated cylinder.
