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?

ivolga24 [154]

Answer:

0.95 kPa

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.
