Acrystallographer measures the horizontal spacing between molecules in a crystal. the spacing is
16.5
nm
. what is the total width of a crystal in millimeters
10^5
molecules across? write your answer as a decimal.

The total width of a crystal is 1.65 mm.

Explanation:

Horizontal length between the two molecules = 16.5 nm

Width of the molecules :

The total width of a crystal in millimeter=

The total width of a crystal is 1.65 mm.

1.65 mm

Given:

A crystallographer measures the horizontal spacing between molecules in a crystal. The spacing is  16.5  nm.

Question:

What is the total width of a crystal in millimeters  that is 10⁵  molecules across?

The Process:

We will solve the problem of unit conversion, especially the unit of length. This time we will convert nanometers to millimeters.

Recall that,

Crystallographers observe 10⁵ molecules across with the intermolecular distance in the crystal is 16.5 nm.

We cross out the same units.

Thus, the total width of a crystal in millimeters is 1.65 mm.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
