Question

(PLEASE HELP) 500 mL of a gas is collected at 745 mmHg. What will the volume be at 1.8 atm?

Answer 1

272.22 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`

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we're finding the new volume we have

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

First convert 745 mmHg to atm

760 mmHg = 1 atm

745 mmHg = 745/760 = 0.98 atm

We have

`V_2 = (500 * 0.98)/(1.8) \\ = 272.222...`

We have the final answer as

272.22 mL

Hope this helps you
