What is the diameter of a molecule?

What is the diameter of a molecule?

The diameter of a molecule, assuming it to be spherical; has a numerical value of 10-8 centimeter multiplied by a factor dependent on the compound or element.

Which is bigger N2 or O2?

O2 and N2 molecules are only slightly different in molecular size but both are very small. O2 does have a greater molecular weight (32) than N2 (28), but O2 is actually smaller in size. Thus, O2 fits through the relatively tight passage ways between polymer chains in the rubber more easily than does N2.

Is O2 smaller than CO2?

13.3. The molecular diameter of CO2 is larger than that of O2, with a value of 3.34 × 10−8 cm. Thus, based on the pore size, film can be selectively permeable to gases.

What is the size of a gas molecule?

Thus, a typical molecule is exceedingly small, and there is an impressively large number of them in one cubic centimetre of gas. Between collisions, a gas molecule travels a distance of about l/d = (2.0 × 10-5)/(3.9 × 10-8) = 500 times its diameter.

What determines the size of a molecule?

The amount of space any mass takes up in three-dimensional space is known specifically as its volume. Using algebra and the density formula discovered by Archimedes of Syracuse, one can determine the molecular size of a molecule for any given mass of molecular substance.

Are molecules different sizes?

Molecules have size and different molecules are different sizes. That is the total weight of all of the atoms in the molecule. So water, which is made up of two hydrogen atoms (1 atomic mass unit each) and one oxygen atom (16 atomic mass units) has a molecular weight of 18 (well, to be exact).

Can a molecule be a single element?

Elements can be made of one atom, like He, or be elemental molecules, such as hydrogen (H2), oxygen (O2), chlorine (Cl2), ozone (O3), and sulfur (S8). Some elements are monatomic, meaning they are made of a single (mon-) atom (-atomic) in their molecular form. Helium (He, see Fig.

Is table salt a molecule or compound?

Something like table salt (NaCl) is a compound because it is made from more than one kind of element (sodium and chlorine), but it is not a molecule because the bond that holds NaCl together is an ionic bond. If you like, you can say that sodium chloride is an ionic compound.
