Two liquids- one polar, one nonpolar- have the same molar mass. Which one has the higher boiling point? Please choose the best answer and explaination. a. it is impossible to say without additional information b. the nonpolar liquid will have the higher boiling point, since its molecules are more loosely held together. c. the nonpolar liquid will have the higher boiling point, since the polar molecules will repel each other and lower the boiling point. d. the polar liquid will have the higher boiling point, since its molecules have dipole-dipole interactions. e. they will have similar boiling points, since the dispersion forces depend upon molar mass
A 0.1276 g sample of a monoprotic acid (molar mass=1.10 x 10^2) was dissolved in 25 mL of water and titrated with 0.0633 M NaOH. After 10 mL of base had been added, the pH was determined to be 5.57. What is the Ka for the acid
