Answer: 103.7 kPa
Step-by-step explanation:
Given that:
initial volume of gas V1 = 445ml
initial pressure of gas P1 = 120 kPa.
new Volume V2 = 515ml
new pressure P2 = ?
Since, only pressure and volume are involved, apply the formula for Boyle's law
P1V1 = P2V2
120 kPa x 445ml = P2 x 515 kPa
53400 = P2 x 515 kPa
P2 = 53400/515
P2 = 103.7 kPa
Thus, the final pressure of the gas is 103.7 kPa
