Question asked by Filo student

2.11 Calculate the mass of ascorbic acid (Vitamin ${\mathrm{C}}_{,},{\mathrm{C}}_6{\mathrm{H}}_8{\mathrm{O}}_f$ ) to be dissolved in $75\mathrm{g}$ of acetic acid to lower its melting point by $1.5^{\circ }\mathrm{C}.{\mathrm{K}}_{\mathrm{r}}=3.9\mathrm{K}\mathrm{kg}\mathrm{mol}$ 2.12 Calculate the osmotic pressure in pascals exerted by a solution prepared by dissolving $1.0\mathrm{g}$ of polymer of molar mass 185,000 in $450\mathrm{mL}$ of water at $37^{\circ }\mathrm{C}$. $2.7$ Abnormal We know that ionic compounds when dissolved in water dissociate into Molar cations and anions. For example, if we dissolve one mole of $\mathrm{KCl}(74.5\mathrm{g})$ Masses in water, we expect one mole each of ${\mathrm{K}}^{\prime }$ and ${\mathrm{Cl}}^{-}$ions to be released in the solution. If this happens, there would be two moles of particles in
