(B) The formula for osmotic pressure is $\pi = iMRT = \frac{i \times W_2 \times R \times T}{M_2 \times V}$.Given values are: $i = 2.47$,$W_2 = 1.7 \ g$,$R = 0.082 \ dm^3 \ atm \ mol^{-1} \ K^{-1}$,$T = 300 \ K$,$M_2 = 111 \ g \ mol^{-1}$,and $V = 1.25 \ dm^3$.Substituting these values into the formula:$\pi = \frac{2.47 \times 1.7 \times 0.082 \times 300}{111 \times 1.25} \ atm$.$\pi = \frac{103.3638}{138.75} \ atm$.$\pi = 0.744 \ atm$.
