Answer:
3:4
Step-by-step explanation:
In N₂O plus NO mixture (X n2o) equals 1/3. But- the mole fraction of NO in a mixture of NO and NO₂ is (3/4).
Therefore, the mole ratio representing no to no2 is 3:4, representing also the fraction, 3/4, with a numerator of 3 and the denominator of 4.
Here is how I got 3/4, (or to be specific, the RATIO, 3:4.)
xNO2 equals 1/3 times 3 = 1. (RATIO)
xNO2 equals 1 - 1/3 = 2/3
