- When 2.43 g of a nonelectrolyte solute is dissolved in water to make 435 mL of solution at 25 °C, the solution exerts an osmotic pressure of 895 torr. What is the molar concentration of the solution? concentration: 0.045 M Incorrect How many moles of solute are in the solution? moles of solute: 0.034 mol Incorrect What is the molar mass of the solute? molar mass: 69.12 g/mol IncorrectA 1.143 g sample contains only vitamin C (C,H, 0,) and sucralose (C,H,Cl, O,). When the sample is dissolved in water to a total volume of 31.7 mL, the osmotic pressure of the solution is 3.91 atm at 285 K. What is the mass percent of vitamin C and sucralose in the sample? vitamin C: sucralose: %A water solution contains 60% Na2S202 together with 1% soluble impurity. Upon cooling to 10°C, Na2S202 • 5 H2O crystallizes out. The solubility of this hydrate is 1.4lb Na2S202 • 5 H20/lb free water. The crystals removed carry asadhering solution 0.06 lb solution/lb crystals. When dried to remove the remaining water (but not the water of hydration), the final dry Na2S202 5 H20 crystals must not contain more than 0.1% impurity. To meet this specification, the original solution, before cooling, is further diluted with water. On the basis of 100 Ib of the original solution,calculate (a) the amount of water added before cooling, and (b) the percentage recoveryof the Na2S202 in the dried hydrated crystals
