Surface pressure in film


The following surface pressure measurements were obtained
for a film of haemoglobin spread on 0.01 mol dm~3 HC1 (aq.) at 25°C:

Calculate the relative molecular mass of the spread protein and
compare your answer with a value of 68000 as determined from
sedimentation measurements.

How can I calculate the relative molecular mass of the spread protein If I know A(area) and surface pressure?
Thank you!
