In the commercial manufacture of nitric acid, how many liters of nitrogen dioxide will produce 30 liters of nitric oxide given that both gases are at STP? 3NO2 + H2O 2HNO3 +NO
A. 20 liters
B. 0.1 liters
C. 40 liters
D. 90 liters
E. 1.01 liters

Respuesta :

At standard pressure and temperature (STP) each mole of gas occupies a volume of 22.4 liters.

The balanced chemical equation signifies that 3 moles of nitrogen dioxide generate 1 mole of nitric oxide.

3 moles × 22.4 = 67.2 liters

1 mole × 22.4 liters = 22.4 liters

67.2 liters of nitrogen dioxide/22.4 liters of nitric oxide = x liters of nitrogen dioxide/30 liters of nitric oxide

Thus, x = 30 liters of nitric oxide × 67.2 liters of nitrogen dioxide / 22.4 liters of nitric oxide = 90 liters of nitrogen dioxide.

the answer is D for plato users
