The answer for the following problem is mentioned below.
- <em><u>Therefore the final moles of the gas is 12.8 moles</u></em>
- <em><u>Therefore the option is "D" (12.8 moles)</u></em>
Explanation:
Given:
Initial moles () = 7.51 moles
Initial volume () = 8.15 L
Final volume () = 13.9 L
To find:
Final moles of the gas
We know;
From 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
we know;
from the above mentioned equation,
V ∝ n
So,
=
where,
represents the initial volume
represents the final volume
represents the initial moles
represents the final moles
So,
=
= 12.8 moles
<em><u>Therefore the final moles of the gas is 12.8 moles</u></em>
