A graduated cylinder has 33.5 mL of water. A piece of metal is added to the water and the new volume is now 46.2 mL. If the metal has a mass of 16.25 g, what is its density

The density of metal is 1.28g/ml

Explanation:

To calculate the density, we use the equation:

Density of metal = ?

Mass of metal = 16.25 g

Volume of metal = volume of water displaced = (46.2 - 33.5 )ml  = 12.7 ml

Putting values in above equation, we get:

The density of metal is 1.28g/ml

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
