Work Step by Step

.460°C = (5.12°C/m)(x) x = .0898 m Using the information, you can find the molal concentration first in order to find the number of moles. The molal freezing-point depression constant of benzene is 5.12°C/m. You can set up an equation, where x = the molal concentration of the solution. Use the molal concentration to find the number of mols of the solute. The given mass of the solute in the mass of the number of moles there are.
