(C) The osmotic pressure formula is $\Pi = CRT$,where $C = \frac{n}{V} = \frac{W_2}{M_2 \times V}$.Substituting the values into the formula: $\Pi = \frac{W_2 \times R \times T}{M_2 \times V}$.Rearranging to solve for mass $(W_2)$: $W_2 = \frac{\Pi \times M_2 \times V}{R \times T}$.$W_2 = \frac{0.245 \ atm \times 58 \ g \ mol^{-1} \times 2.5 \ dm^3}{0.0821 \ dm^3 \ atm \ K^{-1} \ mol^{-1} \times 300 \ K}$.$W_2 = \frac{35.525}{24.63} \approx 1.44 \ g$.
