'hapter $1$ Problem $30,$ Part A$.$

a$.$ Calculate the pressure at Point $B.$

i$.$ Make your file generic so any input could be changed and a new solution calculated. Consider using the "Cell Styles" tolconvey inputs, intermediate calculations, explanations, notes, and key outputs.

b$.$ Plot the pressure of the methane column from Point $A($surface$)$ to Point below surface$).$ Add to this plot two additional gases so we can see the effect of molecular weight $($use ethane and carbon dioxide$).$

i$.$ Make sure your file is annotated so I can follow your logic.

c$.$ Add comments in Excel to convey$/$synthesize your findings $-$ For example: Do the results make sense? How do the results vary with MW$?$ What insights do you get from the plot?
