Question

At 25oC three moles of a gas occupy a volume of 4.0 L at 1.9 kPa If the volume increases to 8.0 L what will the new pressure be?

Answer 1

0.95kPa

Step-by-step explanation:

I've just answered this question and it came out right.

Answer 2

0.95 kPa

Step-by-step explanation:

`P_(1) V_(1) = P_(2)V_(2)`

(4.0)(1.9) = (
`P_(2)`)(8.0)

`P_(2)= 0.95` kPa

-- However, you should see that when the volume increases (doubles, in this case) you will divide the original pressure value by 2. Pressure and volume are inversely related.
