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.

A solution which is composed of heptane (C-H16, 100.198 g mol") and octane (CH13, 114.224 g mol-) has vapor pressure of 78 torr at 40 °C. The saturated vapor at equilibrium with the solution contains 16.55 g heptane and 22.15 g octane. The vapor pressures of pure heptane and pure octane at 40 °C were 92.0 Torr and 31.2 Torr, respectively. What is the mole percent of C3H;3 in the initial solution? Do not write units, only enter numerical values. Use two digits at most for decimal numbers, use dot (.) as decimal separator (i.e. two-point-fifty-one should be entered as 2.51). Do not use comma () as decimal separator.

Which substance is more soluble? CaSO4 (Ksp=7.10x10-5) AgCI(Ksp 1.77x10-10) O CaSO4 O AgCl
