The arerage molar mass i 8
[
begin{array}{r}
M=frac{rho R T}{P}=frac{1.78 / .1 times 0.0821 times 273}{1}
=38.18 / mathrm{mo}
end{array}
]
Let ( x ) be mole fraction of ( C D ). and mole fraction of ( cos ) be ( (1-x) )
molar ragss of 10 sind 60,2 are
28 and 44 respectively.
Arg. molar oruss 7 . Prixture is
