Insulin(C6H10O5)ndissolved in a medium shows osmotic pressureπat C gm/cm3concentration and 300 K temperature. The slope of plot ofπagainst C is4.1×10-3. Molecular mass of insulin is

Options:

Answer:
B
Solution:

πV1000=nRT     V in Cm3
πV=wB×1000MBRT
π=wBV1000RTM=C×1000RTMB
Whenπis plotted against C, the slope will be equal to1000RTMB.
So4.1×10-3=1000×0.082×300MB
MB=6×106.
