Suppose that a sample of gas occupies 119 mL
of volume at 25◦C and a pressure of 221 torr.
What would be the volume if the pressure
were changed to 647 torr at 25◦C?
This is boyle's law right? p1v1 = p2v2
Since I'm looking for v2 I rearranged it to be
v2 = p1v1 / p2
which is (221 torr) (0.119 L) / (647 torr)
(( I changed ml to L because that's what I've been taught in class ))
and then I got 0.04065 L ... I went so far out because the website we use to answer our questions on doesn't round but it says that I'm wrong. Can someone please tell me what I did wrong? Thanks
