Nitrogen gas can be combined with oxygen to form nitric oxide (NO) as shown in the following chemical reaction: N2 (g) + O2 (g) 2 NO (g) When the reaction is in equilibrium, the concentration of N2, O2 and NO are 280 g/L, 640 g/L, and 750 g/L, respectively. If the concentration of oxygen gas dropped to half, calculate the concentration of nitric oxide (NO) in g/L when the system returns to equilibrium. (N=14, O=16 g/mol) Enter your final answer with 2 decimal places.
