H2S is an unwanted byproduct in the pulp and paper industry. To capture the H2S gas it is bubbled through a NaOH solution to produce Na2S with a yield of 94% H2S (g) + 2NaOH (aq) > Na2S (aq) + 2H2O (l) 1. What mass of H2S (g) was processed ( in kg ) if 10.76 kg of Na2S was collected

16. Every year, oral rehydration therapy (ORT) –the feeding of an electrolyte solution -saves the lives of countless children worldwide who become severely dehydrated as a result of diarrhea. One requirement of the solution used is that it be isotonic with human blood. An ORT solution contains 3.5 g NaCl, 1.5 g KCI, 2.9 g Na3C6H507 (sodium citrate), and 20.0 g C6H1206 (glucose) per liter. What is the freezing point of this solution? You may assume that the density of the solution is 1.00 g/mL and that the freezing point depression constant (Kf) for water is 1.86 °C/m. -0.59 оС -1.86 оС 0.00 oC +0.51 oC -7.44 oC
