How much space does 2 x 1022 atoms of copper take up?

How much space does 2 x 10²² atoms of copper take up?

2 x 10²² atoms of copper take up 0.2 cm³.

First, we will convert 2 x 10²² atoms to moles using Avogadro's number (6.02 × 10²³ atoms/mol) as the conversion factor.

Next, we will convert 0.03 moles to grams of copper using its molar mass (63.55 g/mol) as the conversion factor.

Finally, we will convert 2 g of copper to cubic centimeters using its density (8.96 g/cm³) as the conversion factor.

2 x 10²² atoms of copper take up 0.2 cm³.

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.
