Answer:
The answer is
84.9 kPa
Explanation:
Using Boyle's law to find the final pressure
That's
[tex]P_1V_1 = P_2V_2[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the final pressure
[tex]P_2 = \frac{P_1V_1}{V_2} [/tex]
From the question
P1 = 115 kPa
V1 = 480 mL
V2 = 650 ml
So we have
[tex]P_2 = \frac{115000 \times 480}{650} = \frac{55200000}{650} \\ = 84923.076923...[/tex]
We have the final answer as
84.9 kPa
Hope this helps you
