Determine the melting point of an aqueous solution containing 147 mg of saccharin (C7H5O3NS) added to 1.00 mL of water (density of water = 1.00 g/mL, Kf = 1.86°C/m). What is the freezing point of a 1.276 m aqueous solution of aluminum nitrate, Al(NO3)3? The Kfof water is 1.86°C/m.
2. Saccharin is a common artificial sweetener without calories. When 3.00 g of the sodium salt of saccharin (the anion of saccharin with a Na cation) is dissolved in 50.0 mL of water, it takes 14.6 mL of 1.00 M HCl to reach the equivalence point. Using the data provided, calculate the molecular weight of sodium saccharin?

A sugar solution is prepared by adding 3.50 g of sugar to 22.5 mL of a pure liquid and the freezing point of the sugar solution was determined to be -99.84 C. If the normal freezing point of the pure liquid is -97 C and the density is .792g/mL, what is the freezing point depression constant in degrees celsius?
1. Saccharin is an artificial sweetener that was discovered in 1879 when a chemist spilled some of his product on his sandwich, and when he ate his sandwich discovered it was particularly sweet. It is synthesized according to the following reaction and the product is isolated after addition of HCI. -NH₂ + NaOH + KMnO4 NH OS=0 a) What safety rule did our chemist violate when discovering saccharin?
