Question

Nitrogen monoxide is produced by combustion in an automobile engine.  According to the following reaction, how many grams of oxygen gas are required for the complete reaction of 28.9 grams of nitrogen monoxide?

nitrogen monoxide (g) + oxygen (g) nitrogen dioxide (g)

 grams oxygen gas

Answer 1

28.9g NO x (1 mol NO / 30.01g NO) = 0.963 mol NO

0.963 mol NO x (1 mol O₂ / 1 mol NO) = 0.963 mol O₂

0.963 mol O₂ x (31.98g O₂ / 1 mol O₂) = 30.8g O₂

Answer: 38 grams of oxygen gas are required for the complete reaction of 28.9 grams of nitrogen monoxide.
