Expert Answer:

The space reaction space is space as colon

straight N subscript 2 space space plus space space 2 straight O subscript 2 space end subscript space rightwards arrow space 2 NO subscript 2 space space


space space space 1 space gm space of space straight N subscript 2 space will space require space straight X space straight g space of space straight O subscript 2 space end subscript

No. space of space moles space of space of space straight N subscript 2 space end subscript space equals fraction numerator Weight space over denominator Molecular space weight end fraction

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 1 over 14

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 0.071 space mol

As space 1 mol space of space straight N subscript 2 space requires space 2 space mol space of space straight O subscript 2 space end subscript

0.071 space mol space space of space straight N subscript 2 space will space require space space fraction numerator space 0.071 space cross times 2 over denominator 1 end fraction

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 0.142 space mol space of space straight O subscript 2

space No. space of space moles space space equals fraction numerator Weight space over denominator Molecular space weight end fraction

therefore space space space space space space space space space Weight space of space space space straight O subscript 2 space space equals space space space space No. space of space moles space space cross times space space space Molecular space weight

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 space space space space 0.142 space cross times space 16

space space space space space space space space space space space space space Weight space of space space space straight O subscript 2 space space equals space 2.272 space straight g space of space straight O subscript 2
 
weight of oxygen required to combine with 1 g of nitrogen to form an oxide is 2.27 g.
