Answer:
The groupings of elements in the periodic table reveal various trends, present in groups such as the alkali metals and noble gases, or the lanthanides and actinides. The periodic table can be used to find information on elements or predict the properties of as-of-yet undiscovered elements.
Explanation:
The method is called the displacement method.
You place some water in the graduated cylinder and measure its volume.
Then you add your object and measure the new volume.
The difference between the two volumes is the volume of your object.
Molecular mass of H2O is: 16+2*1=18
so moles of 40g of H2O is: 40/18=2.22

So take that number and multiply it by 6.75.
You then get... 297.0641
Have a nice day.
