Question

The air in a syringe has volume 25.0 mL
when the pressure is 4.38 atm. What will be
its volume when the pressure is 0.65 atm?

Answer 1

Answer:

168.46 mL

Explanation:

The new volume can be found by using the formula for Boyle's law which is

$P_1V_1 = P_2V_2$

Since we are finding the new volume

$V_2 = \frac{P_1V_1}{P_2}$

From the question we have

$V_2 = \frac{25 \times 4.38}{0.65} = \frac{109.5}{0.65} \\ = 168.46153...$

We have the final answer as

168.46 mL

Hope this helps you
