What is the boiling point of an aqueous solution of a nonelectrolyte that has an osmotic pressure of 10.50 atm at 25°C? K_b of water is 0.52°C/m. Assume the density of the solution is the same as that of pure water. A)0.22°C B)0.429°C C)100.43°C D)99.78°C E)100.22°C

The boiling point elevation can be calculated using the formula ΔT_b = iK_bm, where i is the van't Hoff factor (1 for nonelectrolytes), K_b is the ebullioscopic constant, and m is the molality. First, calculate molality using the osmotic pressure formula π = MRT, where R is the gas constant and T is the temperature in Kelvin. Then, use the calculated molality to find ΔT_b and add it to the normal boiling point of water (100°C).
