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.
or,
where,
= initial pressure of gas = 650 mmHg = 0.855 atm (1 atm = 760 mmHg)
= final pressure of gas = 1.6 atm
= initial volume of gas = 220 mL
= final volume of gas = ?
Now put all the given values in the above equation, we get:
Therefore, the final volume of the cylinder is, 117.6 mL
