Question

How many liters of ammonia are produced when 3.0 moles of water and 3.0 moles of nitrogen dioxide are reacted to completion at STP conditions

Answer 1

The number of ammonia in liters produced is calculated as follows

write the reacting equation

4NO2 +6H2O = 4NH3 + 7 O
H2O is the limiting reactant since 3 moles of H20 reacted completely with 3 x4/6 = 2 moles of NO2

At STP 1 mole = 22.4 L what about 2 moles

= 2 / 1 x22.4 =44.8 liters of ammonia
