As a result of air at the top of a barometer, the height of the mercury column is 73.5cm when it should be 75.0cm; the volume of the space above the mercury is 8.0cm3. Calculate the correct barometer height when the barometer reads 74.0cm and the volume of the space above the mercury is 6.0cm3.

Michelle this is the workings you asked for, even if you use the other way round, which is p1v1=p2v2, u will still arrive at the same answer!

Try calculating it too, the answer is C
you will get 75.125 as your ans and if you approximate it, it will give you 75.1 not 76cm
please checkmate answer
