Question: please help WITH ALL THREE PROBLEMS. please dont attempt if you are only solving one What is the freezing point of a solution containing 15.56g

please help WITH ALL THREE PROBLEMS. please dont attempt if you are only solving one

are only solving one What is the freezing point of a solution

What is the freezing point of a solution containing 15.56g 3,5-dimethylanisole (C9H12O), a nonelectrolyte, and 198.4g acetic acid (CH3COOH) ? The normal freezing point of acetic acid is 16.60C and Kpp for acetic acid is 3.90C/m. Calculate the boiling point of a solution. What is the boiling point of a solution containing 28.54g of the nonvolatile nonelectrolyte diphenylether (C12H10O) and 270.2g of ether (C2H5OC2H5) ? The normal boiling point of ether is 34.5C and Kbp for ether is 2.02C/m. In a laboratory experiment, a student found that a solution consisting of 45.97g of an unknown compound (a nonvolatile nonelectrolyte) and 266.2g of C2H5OH has a boiling point of 79.77C. The normal boiling point of C2H5OH is 78.50C. What is the molar mass of the compound? ( Kbpbp=1.22C/m for C2H5OH)
