1.	7.45 g of ionic solid dissolved in 1 L of solution at 300 K and osmotic pressure of this solution at 300 K is 4.92 atm (assume solid is fully ionised). Density of crystal of ionic solid is 31.79 g/cm3. If the number of cations and anions per unit cell are X and Y, then the value of (X + Y) is [Molar mass of ionic solid is 74.5 g/mol. R = 0.082 atm Lmol K,NA=6×1023 and edge length of cubic crystal of ionic solid is 2.5 A]
Answer» 7.45 g of ionic solid dissolved in 1 L of solution at 300 K and osmotic pressure of this solution at 300 K is 4.92 atm (assume solid is fully ionised). Density of crystal of ionic solid is 31.79 g/ $c m^{3}$ . If the number of cations and anions per unit cell are X and Y, then the value of (X + Y) is [Molar mass of ionic solid is 74.5 g/mol. R = 0.082 $\frac{a t m L}{m o l K}, N_{A} = 6 \times 10^{23}$ and edge length of cubic crystal of ionic solid is 2.5 A]
