Nitrogen reacts with hydrogen to produce ammonia gas as follows. mc023-1.jpg how many moles of nitrogen would react with excess hydrogen to produce 520 ml of ammonia? 0.0116 mol 0.012 mol 0.0232 mol 0.024 mol

n = PV / RT = 1.00(.520 L) / (0.08206 atm L/mol K ) 273 K
n= 0.0232 mol NH3

0.0232 mol NH3 (1 mol N2 / 2 mol NH3) = 0.0116 mol N2

Therefore, the correct answer is A.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
