A solution is made by dissolving 13 g of sucrose,C₁₂H₂₂O₁₁,in 117 g of water,producing a solution with a volume of 125 mL at 20°C.What is the expected osmotic pressure at 20°C? A)7)3 atm B)10 atm C)14 atm D)58 atm

Question

Quizplus · Accepted Answer

The correct answer is A because the osmotic pressure is calculated using the formula: osmotic pressure = M * R * T, where M is the molarity of the solution, R is the ideal gas constant (0.0821 L * atm / (mol * K)), and T is the temperature in Kelvin. The molarity of the solution is calculated by dividing the number of moles of solute by the volume of the solution in liters. The number of moles of solute is calculated by dividing the mass of solute by its molar mass. The molar mass of sucrose is 342.3 g/mol. Therefore, the molarity of the solution is:molarity = (13 g / 342.3 g/mol) / (125 mL * 1 L / 1000 mL) = 0.029 MThe osmotic pressure is then calculated as:osmotic pressure = 0.029 M * 0.0821 L * atm / (mol * K) * (20°C + 273.15 K) = 7.3 atm
