So many chemistry calculations, this problem can be worked using the unit analysis thought process and format. We start by identifying the unit that we want to arrive at (kg H 2O) and a known value that can be used to start the unit analysis setup ( × kg P 4O 10).

We have already decided that we will convert from amount of P 4O 10 to File Size: 1MB. A To calculate the work done, we need to know the initial and final volumes. The final volume is the volume of one of the six cylinders with the piston all the way down: V f = L/6 = L.

With a compression ratio, the volume of the same cylinder with the piston all the way up is V i = L/10 = L. Work is done by the.
