A sample of hydrogen occupies a volume of 3.20L at a pressure of 425 kPa. If the temperature of the gas kept constant, what would be the new volume of the gas at
615 kPa?

Answer 1

2.2 L

Step-by-step 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're finding the new volume

`V_2 = (P_1V_1)/(P_2) \\`

425 kPa = 425,000 Pa

615 kPa = 615,000 Pa

`V_2 = (3.2 * 425000)/(615000) = (1360000)/(615000) \\ = 2.21138...`

We have the final answer as

2.2 L

Hope this helps you
