Calculate the actual work done on the 200 g mass using W = mgh.  Be careful to use only the change in height of the mass.  How does this compare to the work done by the gas from step C?  Does the gas do any work other than lifting the 200 g mass?

Question

Calculate the actual work done on the 200 g mass using W = mgh.  Be careful to use only the change in height of the mass.  How does this compare to the work done by the gas from step C?  Does the gas do any work other than lifting the 200 g mass? (The picture contains the data).
