Question

25.0 grams of NO and excess oxygen react in a sealed container.

What is the theoretical yield of NO2?

[?] g NO₂

Answer 1

lculate moles of NO:

Moles of NO=Mass of NOMolar mass of NO=25.0 g29.01 g/molMoles of NO=Molar mass of NOMass of NO​=29.01g/mol25.0g​Use mole ratio from the balanced equation:

Moles of NO2=2×(Moles of NO)Moles of NO2​=2×(Moles of NO)Calculate theoretical yield of NO₂:

Theoretical yield of NO2=(Moles of NO2)×(Molar mass of NO2)Theoretical yield of NO2​=(Moles of NO2​)×(Molar mass of NO2​)Plug in the values and compute the result for the theoretical yield of NO₂ in grams.
