You submerge an aluminum block into a large graduated cylinder and notice that the water displaces by 15ml. what is the mass of the aluminum block?

The answer is: the mass of the aluminum block is 40.5 grams.

V(Al) = 15 mL; mass of aluminium block.

d(Al) = 2.7 g/mL; density of aluminium.

m(Al) = V(Al) · d(Al).

m(Al) = 15 mL · 2.7 g/mL.

m(Al) = 40.5 g; mass of aluminium block.

Density is a measure of mass per unit of volume (in this example grams per milliliter).

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
