Answer:
7.5 atm
Explanation:
Given that,
Initial volume, V₁ = 15 L
Pressure, P₁ = 2.1 atm
Final volume, V₂ = 4L
We need to find the final pressure. The mathematical relation between volume and pressure is given by :
[tex]\dfrac{V_1}{V_2}=\dfrac{P_2}{P_1}\\\\P_2=\dfrac{V_1P_1}{V_2}\\\\P_2=\dfrac{15\times 2}{4}\\\\P_2=7.5\ atm[/tex]
So, the final pressure is equal to 7.5 atm.
