When (8.09x10^1) g of a non-electrolyte is dissolved in (5.9500x10^2) g of a solvent (with Kp = 0.416°C/m) the boiling point of the solution is 1.50°C higher than the boiling point of the pure solvent. What is the molar mass (in g/mol) of the non- electrolyte solute? Enter your answer in scientific notation with 3 sig figs. Do not include any units in your answer. Do not round any intermediate calculations. Note: Your answer is assumed to be reduced to the highest power possible.

When (8.09x10^1) g of a non-electrolyte is dissolved in (5.9500x10^2) g of a solvent
(with Kp = 0.416°C/m) the boiling point of the solution is 1.50°C higher than the
boiling point of the pure solvent. What is the molar mass (in g/mol) of the non-
electrolyte solute?
Enter your answer in scientific notation with 3 sig figs. Do not include any units in
your answer.
Do not round any intermediate calculations.
Note: Your answer is assumed to be reduced to the highest power possible.
