Ethanol has a kb of 1.22 degrees c/m and usually boils at 78.4 degrees celcius. how many mol of an nonionizing solute would need to be added to 47.84 g ethanol in order to raise the boiling point to 86.30?

0.3097 moles of an nonionizing solute would need to be added.

Explanation:

Molal elevation constant =

Normal boiling point of ethanol =

Boiling of solution =

Moles of nonionizing solute = n

Mass of ethanol (solvent) = 47.84 g

Elevation boiling point:

n = 0.3097 mol

0.3097 moles of an nonionizing solute would need to be added.
