Answer to Question #86925 in General Chemistry for Krystal

Question

Nitrogen dioxide reacts with water to produce oxygen and ammonia. Using the ideal gas law equation, calculate the grams of NH3 that can be produced when 4.5p L of NO2 react at a temperature of 415 degrees Celsius and a pressure of 715mm Hg.

Answer 1

Solution.

2NO2+3H2O=2NH3+2.5O2

pV=nRT

n(NO2)=pV/RT

n(NO2)=95325.5*4.5/8.31*688=75.03 mole

n(NO2)=n(NH3)

m(NH3)=n(NO2)*M(NH3)

m(NH3)=75.03*14=1275.51 g

Answer:

m(NH3)=75.03*14=1275.51 g
