The answer for the following problem is mentioned below.
- <u><em>Therefore the final volume of the gas is 100 ml.</em></u>
Explanation:
Given:
Initial pressure () = 600 mm of Hg
Final pressure () = 1200 mm of Hg
Initial volume () = 200 ml
To find:
Final volume ()
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 moles of the gas
R represents the universal gas constant
T represents the temperature of the gas
So,
From the above mentioned equation,
P × V = constant
=
Where,
() represents the initial pressure of the gas
() represents the final pressure of the gas
() represents the initial volume of the gas
() represents the final volume of the gas
So;
=
= 100 ml
<u><em>Therefore the final volume of the gas is 100 ml.</em></u>
