Question

Convert 265 torr to pascals.

265 torr= ? Pa
(760 torr= 1.01325*10^5)

How do I go about solving this?

Answer 1

265 torr x (101325*10^5 Pa/760 torr) = ?? Pa.
Note that we started with the unit we wish to convert and multiplied by a factor (in the problem but you could have looked it up) that cancels the unit we don't want (in this case Torr) and leaves the unit we want (in this case Pa). All conversions work this way.
