Question

The plot of osmotic pressure (\Pi) vs concentration (\mathrm{mol\,L^{-1}}) for a solution gives a straight line with slope 25.73\ \mathrm{L\,bar\,mol^{-1}}. The temperature at which the osmotic pressure measurement is done is (use R = 0.083\ \mathrm{L\,bar\,mol^{-1}\,K^{-1}}):

Vishal Gupta · Accepted Answer

D. \Pi = CRT, so the slope of \Pi against C is RT: T = \frac{25.73}{0.083} = 310 K = 37^\circC.
