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

The answer is 223.0 cm³

Step-by-step 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 = (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 = (99300 * 455)/(202600) = (45181500)/(202600) \\ = 223.008390...`

We have the final answer as

223.0 cm³
