Question

define molality and mole fraction

Answer 1

Molality (m) is defined as the number of moles of solute per kilogram of solvent. ... Molarity is a measurement of the moles in the total volume of the solution, whereas molality is a measurement of the moles in relationship to the mass of the solvent


Mole fraction is a unit of concentration, defined to be equal to the number of moles of a component divided by the total number of moles of a solution. Because it is a ratio, mole fraction is a unitlessexpression

Answer 2

hey mate!!!!
Molality-defined to be equal to the number of moles  of solute divided by the number of kilograms of solvent.
Mole fraction-the ratio of the number of moles of one component of a solution or other mixture to the total number of moles representing all of the components.
