Question

sample of helium gas has a volume of 2.0 L at a pressure of 4.0 atm. What is the volume of gas of 17.2 atm

Answer 1

Answer:

0.47 L

Explanation:

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

$P_1V_1 = P_2V_2$

Since we are finding the new volume

$V_2 = \frac{P_1V_1}{P_2}$

From the question we have

$V_2 = \frac{2 \times 4}{17.2} = \frac{8}{17.2} \\ = 0.46511...$

We have the final answer as

0.47 L

Hope this helps you
