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

168.46 mL

Step-by-step 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 = (P_1V_1)/(P_2) \\`

From the question we have

`V_2 = (25 * 4.38)/(0.65) = (109.5)/(0.65) \\ = 168.46153...`

We have the final answer as

168.46 mL

Hope this helps you
