Question

Molos mass of Ae mirtuc ( =27 cdot 6 times 2=55-2 y )
1et ( x ) motes of ( N, 04 ) ke persit in 100 mole metare
[
begin{array}{l}
S_{theta}(100-x) times 46+92 x=100 times 552
Rightarrow 100-x+2 x=frac{5520}{46}
end{array}
]
[
100+x=120
]
Heove Thate fuction of
[
x=20
]
N204 in mudule
( Rightarrow frac{20}{100} Rightarrow 0.2 )
