Ammonia gas (a valuable chemical reactant) can be formed by the reaction of nitrogen with hydrogen according to the equation: N2(g) + 3H2(g) → 2NH3(g) In a particular reaction, [nitrV] L of nitrogen gas (measured at a pressure of [nitrP] Pa and a temperature of [nitrT] °C) mixes with [hydrV] L of hydrogen (measured at a pressure of [hydrP] Pa and a temperature of [hydrT] °C). The reaction produces [ammV] L of ammonia gas at STP. What is the percent yield of the reaction? Enter your answer to one decimal place and without units.
