Question

What would be the new pressure if a 400 mL gas sample at 380 mm Hg is expanded to 800 mL with no change in temperature

Answer 1

25 atm or 190mmHg

Step-by-step explanation:

Since Temperature is constant we dont need to worry about it so.

P1V1=P2V2

Rewritten as (P1xV1)/V2 Always use liters in gas laws

I Prefer atm so ill convert to that to use in the equation.

(.5atmx.4L)/.8L =.25 atm or 190mmHg

(You can convert mmHg to atm by dividing by 760)
