Given molecule:
CH3-CH2-CH2-CH2-CH2-CH2-CH3
- The molecule contain only C and H atoms, hence it is a hydrocarbon
- The C atoms in the linear chain are linked together by carbon-carbon single bonds, hence it is a saturated compound
- It has 7 C atoms and 16 H atoms, hence the molecular formula is C7H16
-The molecular formula can be generally represented as CnH2n+2 where n = 7. This corresponds to the general molecular formula for alkanes
The given molecule is best described as an <u>alkane</u>
Explanation:
Let us assume that volumes is equal to spheres volume of nucleus.
fm = femto meter =
pm = pico meter =
Hence, calculate the volume as follows.
V =
=
= 82.4481
(cubic femtometers)
or, = 82
Now, we will calculate the volume of the atom as follows.
V =
=
= 1436758.4
(cubic picometers)
thus, we can conclude that volume of the nucleus is 82
and volume of the atom is 1436758.4
.
I assume about 5 atoms are in one molecule of this product
