The freezing point of 52.71 g of a pure solvent is measured to be 41.99 ºc. when 2.14 g of an unknown solute (assume the van 't hoff factor = 1.) is added to the solvent the freezing point is measured to be 39.61 ºc. answer the following questions ( the freezing point depression constant of the pure solvent is 7.52 ºc·kg solvent/mol solute).
what is the molality of the solution?
m
how many moles of solute are present?
mol
what is the molecular weight of the solute?
g/mol
the freezing point of 50.37 g of a pure solvent is measured to be 42.22 ºc. when 2.53 g of an unknown solute (assume the van 't hoff factor = 1.) is added to the solvent the freezing point is measured to be 39.41 ºc. if the freezing point depression constant of the pure solvent is 7.23 ºc·kg solvent/mol solute calculate the molar mass of the solute.
