To appreciate what that concentration means, calculate the volume of water that you would need to dissolve 1.0 g (about 1 teaspoon) of epinephrine to a concentration equal to that in blood.

Calculate the molarity and molality of the student's solution. Round both of your answers to 2 significant digits. molarity = molality =
Which of the following is the best molecular level description of what happens when CH30H is added to water? A. A solution forms when the London forces between solute molecules are broken and substituted by London forces that keep solvent molecules together. B.A solution forms due to the large ion-dipole forces that produce a strong attraction between solute and solvent molecules. OC. The hydrocarbon portion of the CH3OH repels the water molecules, which prevents a solution from forming D.A solution forms because the forces that keep solvent molecules together are replaced by solvent- solute forces; these forces include hydrogen bonds.
