Expert Answer:

vapour space density space of space mixture space equals space 38.3

Molar space mass space of space the space mixture space equals space 2 cross times space 38.3 space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space
space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals space 76.6
No. space of space moles space in space 100 space straight g space of space mixture space equals space fraction numerator 100 over denominator 76.6 end fraction

Let space x space straight g space of space NO subscript 2 space end subscript is space present space in space 100 space straight g space mixture. space therefore Mass space of space straight N subscript 2 straight O subscript 4 space equals space 100 minus straight x space straight g

Moles space of space NO subscript 2 space plus space Moles space of space straight N subscript 2 straight O subscript 4 space equals space Moles space of space mixture

x over 46 space plus space fraction numerator left parenthesis 100 minus x right parenthesis space over denominator 92 end fraction space equals space fraction numerator 100 over denominator 76.6 end fraction space space equals space x space equals 20.10 space straight g

Moles space of space NO subscript 2 space in space mixture space equals space fraction numerator 20.10 over denominator 46 end fraction space equals space 0.437
