Solve Water Displacement: General Chemistry Question

[PhHsSuga05]

I have another chem question, this time about water displacement. All i need is how to start it...the steps...not the ACTUAL WORK FOR THE PROBLEM

The density of Solid A is 2.70 g/cm3 and that of Solid B is 1.79 g/cm3. A 6.86-g sample of Solid A is transferred to a graduated cylinder containing 5.00 mL of water and a 7.11-g sample of Solid B is transferred to a graduated cylinder, also containing 5.00 mL of water. Which solid sample displaces the larger volume of water? By how many mililiters?

I have like 12 of these types of problems...and don't even know how to start.
thanks

To solve this water displacement problem, you will need to use the formula for density: Density = mass/volume. First, you will need to determine the volume of each solid sample by using the formula for volume of a cylinder: Volume = πr^2h. Then, you can calculate the density of each solid by dividing its mass by its volume. Once you have the densities of both solids, you can compare them to see which one is denser. The denser solid will displace a smaller volume of water. To find the difference in volume, you can subtract the volume of water displaced by Solid A from the volume of water displaced by Solid B. This will give you the amount of water displaced by Solid B in excess of Solid A. I hope this helps you get started on solving your water displacement problems.
