Answer : The final pressure of the gas is, 2.12 atm
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
[tex]P\propto \frac{1}{V}[/tex]
or,
[tex]P_1V_1=P_2V_2[/tex]
where,
[tex]P_1[/tex] = initial pressure of gas = 1.20 atm
[tex]P_2[/tex] = final pressure of gas = ?
[tex]V_1[/tex] = initial volume of gas = 2.65 L
[tex]V_2[/tex] = final volume of gas = 1.50 L
Now put all the given values in the above equation, we get:
[tex]1.20atm\times 2.65L=P_2\times 1.50L[/tex]
[tex]P_2=2.12atm[/tex]
Therefore, the final pressure of the gas is, 2.12 atm
