# The boiling point of a solution containing 10.44g og an unknown nonelectrolyte in 50g of acetic acid is 159.2 degree celsius. What is the molar mass of the solute?

We're asked to find the molar mass of the solute, given some known information about boiling-point elevation.

To do this, we'll be using the equation

where

Plugging in known values:

The molality (moles of solute per kilogram of solvent) is

So

Finally, we can use the given number of grams of solute and this to find its molar mass:

To find the molar mass of the solute, first calculate the molality of the solution using the formula: molality (m) = moles of solute / mass of solvent in kg

Then, use the formula for boiling point elevation: ΔTb = i * Kb * m

Rearrange the equation to solve for moles of solute: moles of solute = ΔTb / (i * Kb)

Finally, calculate the molar mass of the solute using the formula: Molar mass = (mass of solute / moles of solute)
