Question

( 20.1 .05 times 2.1602 . b 4 ) mass is brese It means in 100 g U SOlution ( 20 mathrm{g} ) of ethylene ( 214 cos ) and 80 g of water is present
Now, molar mass of ( c_{2} n_{6} 0_{2}=62 mathrm{g} / mathrm{mod} )
moles of ( c_{2} mathrm{H}_{6} mathrm{O}_{2}=20 / 62 )
[
begin{array}{l}
=0.322 mathrm{mols}
text { moks } y, quad n_{20}=frac{80}{15}
end{array}
]
mole frection of ( c_{2} n_{6} 0_{2} ) i 8
[
frac{0 cdot 322}{0 cdot 322+49 cdot 44}
]
[
=0 cdot 068
]
