Answer:
Option C (1.2 L) is the correct option.
Explanation:
The given values are:
Pressure,
[tex]P_1=1.9 \ atm[/tex]
[tex]P_2=3.8 \ atm[/tex]
Volume,
[tex]V_1=2.3 \ L[/tex]
[tex]V_2=?[/tex]
As we know,
The gas equation is:
⇒ [tex]PV=nRT[/tex]
At constant temperature,
⇒ [tex]P_1 V_1=P_2 V_2[/tex]
or,
⇒ [tex]V_2=\frac{P_1 V_1}{P_2}[/tex]
By substituting the values, we get
⇒ [tex]=\frac{1.9\times 2.3}{3.8}[/tex]
⇒ [tex]=\frac{4.37}{3.8}[/tex]
⇒ [tex]=1.15 \ L[/tex]
or,
⇒ [tex]=1.2 \ L[/tex]
