Question

The volume of CO2 at 99.3 kPa was measured at 455 cm3. What will the volume be if the pressure is adjusted to 202.6 kPa?

Answer 1

Answer:

The answer is 223.0 cm³

Explanation:

To find the volume when the pressure is at 202.6 kPa we use 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 are finding the final volume

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

From the question

P1 = 99.3 kPa = 99300 Pa

V1 = 455 cm³

P2 = 202.6 kPa = 202600

So we have

$V_2 = \frac{99300 \times 455}{202600} = \frac{45181500}{202600} \\ = 223.008390...$

We have the final answer as

223.0 cm³

Hope this helps you
