A sample of oxygen gas occupies a volume of 229.5 mL at 762.7 torr pressure. What volume in mL will it occupy at 704.5 torr pressure?

248.4 mL

Explanation:

In order to answer this problem we can use Boyle's law, which states that at a constant composition:

Where in this case:

We input the data:

And solve for V₂:

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
