Answer:
It is buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.

The answer for the following problem is mentioned below.
- <u><em>Therefore the final  moles of the gas is 14.2 × </em></u> <u><em> moles.</em></u> <u><em> moles.</em></u>
Explanation:
Given:
Initial volume ( ) = 230 ml
) = 230 ml
Final volume ( ) = 860 ml
) = 860 ml
Initial moles ( ) = 3.8 ×
) = 3.8 × moles
 moles
To find:
Final moles ( )
)
We know;
According to the ideal gas equation;
     P × V = n × R × T
where;
P represents the pressure of the gas
V represents the volume of the gas
n represents the no of the moles of the gas
R represents the universal gas constant
T represents the temperature of the gas
So;
     V ∝ n
 =
 = 
where,
( ) represents the initial volume of the gas
) represents the initial volume of the gas 
( ) represents the final volume of the gas
) represents the final volume of the gas
( ) represents the initial  moles of the gas
) represents the initial  moles of the gas
( ) represents the final moles of the gas
) represents the final moles of the gas
Substituting the above values;
     =
 = 
    = 14.2 ×
 = 14.2 ×  moles
 moles
<u><em>Therefore the final  moles of the gas is 14.2 × </em></u> <u><em> moles.</em></u>
<u><em> moles.</em></u>
