Answer 1

The correct balanced decomposition reaction of Nitrogen pentoxide i.e ( N_{​​​​​​2}​​​​​O_​5 is

2N2O5 --- 4NO2 + O2

So , by stoichiometry ,

2 moles of N2O5 gives = 1 mole of O2

Or (2 x 108.01 ) g of N2O5 gives = 32 g of O2

So, 19.19 g of N2O5 produced = [ 32 x 19.19 ] / [ 2 x 108.01 ]

= 2.84 g of O2

hence the correct answer is 2.84 g of O2 will produced .
