A) Determine the freezing point of an aqueous solution created from 3.5 g of Na3PO4 added to 120.0 g of water. The molal freezing point depression constant of water is 1.86 °C/m. Report your answer to 2 significant figures in degrees celcius but do not type in the units. B) For the first order reaction 2X --> N + 3P, the half life is measured as 50 seconds. If the initial solution concentration is 3 M, how long must the reaction proceed to consume 30% of the original amount of X? Give your answer in seconds.
