Vitamin K is involved in normal blood clotting. When 1.45 g of vitamin K is dissolved in 25.0 g of camphor, the freezing point of the solution is lowered by 4.85 °C. The freezing point and Kt constant for camphor can be found here. Calculate the molar mass of vitamin K. Number g/mol Biphenyl, C12H1o, is a nonvolatile, nonionizing solute that is soluble in benzene, C6H At 25 °C, the vapor pressure of pure benzene is 100.84...
