A sample of metal has a mass of 16.63 g, and a volume of 7.94 mL. What is the density of this metal?

The density of the metal is 2.094 g/mL.

Explanation :

Given,

mass of metal sample = 16.63 grams

Volume = 7.94 mL.

Density = ?

Density of the metal can be found by using the formula

Density = Mass/Volume

Substituting the values we get,

density = 16.63/7.94

by solving,

density = 2.094 g/mL.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
