(For #1-3) Mr Wangxian installed a pneumatic piston near his door that is triggered to lock the door in case of an attack and placed 13.0 grams of NaN3 in the empty piston. It is powered by the reaction below: 2 NaN3 (0) → 2 Na w) + 3 N2(g) 1. How many moles of NaN3 was available for the reaction? (Molar mass of NaN3 is 65 g/mol) A. 0.2 mol C. 0.1 mol B. 0.3 mol D. 0.4 mol 2. Assuming that all of the NaN3 reacted, how many moles of nitrogen gas was formed? A. 0.2 mol C. 0.1 mol D. 0.4 mol B. 0.3 mol 3. Assuming that all of the NaN3 reacted and the volume occupied by the solid sodium is negligible, what is the final volume of the piston? 7 A. 6.27 L C. 6.72 L B. 7.26 L D. 2.76 L
