Question

(PLS HELP ASAP <3)

a sample of oxygen gas occupies 600mL when the pressure is 900 mmHg, what is the pressure if the volume is increased to 800 mL​

Answer 1

675 mmHg

Step-by-step explanation:

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

`P_1V_1 = P_2V_2`

Since we're finding the new pressure

`P_2 = (P_1V_1)/(V_2) \\`

We have

`P_2 = (900 * 600)/(800) = (540000)/(800) \\ = 675`

We have the final answer as

675 mmHg

Hope this helps you
