Yes layers of sediment form at the bottom of the ocean.
In the Lewis symbol for a fluorine atom, there are <u>4</u> paired and <u>1</u> unpaired electrons.
However, paired electrons simply means are 2 electrons occupying the same orbital in an atom or molecule of a substance
On the other end, unpaired electron is a single electron that occupies an orbital of an atom.
<h3>What is an atom?</h3>
An atom is the smallest part of an element which can take part in a chemical reaction.
Some atoms of elements are:
- Monoatomic
- Diatomic
- Triatomic
- Polyatomic
In conclusion, in the Lewis symbol for a fluorine atom, there are 4 paired and 1 unpaired electrons.

Based on the data given, the molar mass of the gas is 165.5 g/mol while the molecular weight of the gas is 165.5 amu
<h3>How can molar mass of a gas be obtained from density, temperature and pressure?</h3>
The molar mass of a gas can be obtained from density, temperature and pressure using the formula below:
- molar mass = density × molar gas constant × temperature/pressure
Molar gas constant, R = R = 0.082 L.atm/mol/K.
Temperature = 150 °C = 423 K
Pressure = 785 torr = 1.033 atm
density = 4.93 g/L
molar mass of gas = 4.93 × 0.082 × 423/1.033
molar mass of gas = 165.5 g/mol
Then, molecular weight of the gas = 165.5 amu
Therefore, the molar mass of the gas is 165.5 g/mol while the molecular weight of the gas is 165.5 amu
