This is an incomplete question, here is a complete question.
The air in the cylinder with a piston has a volume of 220 mL and a pressure of 650 mmHg.
If the pressure inside the cylinder increases to 1.6 atm, what is the final volume, in milliliters, of the cylinder?
Answer : The final volume of the cylinder is, 117.6 mL
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 = 650 mmHg = 0.855 atm (1 atm = 760 mmHg)
[tex]P_2[/tex] = final pressure of gas = 1.6 atm
[tex]V_1[/tex] = initial volume of gas = 220 mL
[tex]V_2[/tex] = final volume of gas = ?
Now put all the given values in the above equation, we get:
[tex]0.855atm\times 220mL=1.6atm\times V_2[/tex]
[tex]V_2=117.6mL[/tex]
Therefore, the final volume of the cylinder is, 117.6 mL
